Using double-sided surface mount construction and synchronous rectification technology, these regulators deliver up to 6 A of output current while occupying a PCB area of about half the size of a standard postage stamp. They are an ideal choice for applications where space, performance and cost are important design constraints. The series operates from an input voltage of 12 V to provide step-down power conversion to a wide range of output voltages. W-suffix devices are adjustable from 1.2 V to 5.5 V, and L-suffix devices are adjustable from 0.8 V to 1.8 V. The out- put voltage is set within the adjustment range using a single external resistor. Operating features include an on/off inhibit, output voltage adjust (trim), and the ability to start up into an existing output voltage or prebias. A non-latching over-current trip provides protection against load faults. Target applications include telecom, industrial, and general purpose circuits, including low-power dual-voltage systems that use a DSP, microprocessor, or ASIC. Package options include both throughhole and surface mount configurations.

Pin Descriptions Vin: The positive input voltage power node to the module, which is referenced to common GND. Vout: The regulated positive power output with respect to the GND node. GND: This is the common ground connection for the ‘Vin’ and ‘Vout’ power connections. It is also the 0 VDC reference for the ‘Inhibit’ and ‘Vo Adjust’ control inputs. Inhibit: The Inhibit pin is an open-collector/drain negative logic input that is referenced to GND. Applying a lowlevel ground signal to this input disables the module’s output and turns off the output voltage. When the Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left opencircuit, the module will produce an output whenever a valid input source is applied.

During the power-up period, internal soft-start circuitry slows the rate that the output voltage rises. This reduces the in-rush current drawn from the input source. The soft-start circuitry also introduces a short time delay (typically 12 ms) into the power-up characteristic. The delay is from the point that a valid input source is recognized, to the initial rise of the output voltage. Figure 3-1 shows the powerup characteristic of the PTH12000W with the output voltage set to 5-V. The waveforms were measured with a 2-A resistive load. The initial rise in input current when the input voltage first starts to rise is the charge current drawn by the input capacitors. Figure 3-1 The power modules function normally when the Inhibit pin is left open-circuit, providing a regulated output whenever a valid source voltage is connected to Vin with respect to GND. Figure 3-2 shows the typical application of the inhibit function. Note the discrete transistor (Q1). The Inhibit pin has its own internal pull-up to V in potential. An open-collector or open-drain device is recommended to control this input. Turning Q1 on applies a low voltage to the inhibit control and disables the output of the module. If Q1 is then turned off, the module will execute a soft-start power-up. A regulated output voltage is produced within 25 msec. Figure 3-3 shows the typical rise in both the output voltage and input current, following the turn-off of Q1. The turn off of Q1 corresponds to the rise in the waveform, Vinh. The waveforms were measured with a 5-V output and 2-A resistive load.

Applying a load that exceeds the module’s over-current threshold will cause the regulated output to shut down. Following shut down the module will periodically attempt to recover by initiating a soft-start power-up. This is often described as a “hiccup” mode of operation, whereby the module continues in the cycle of successive shut down and power up until the load fault is removed. During this period, the average current flowing into the fault is significantly reduced. Once the fault is removed, the module automatically recovers and returns to normal operation.

(Note: This is a feature enhancement for the the W-suffix version; see note 1). the Inhibit pin is held low, and whenver the output is allowed to rise under soft-start control. Power up under soft-start control occurs upon the removal of the ground signal to the Inhibit pin (with input voltage applied), or when input power is applied. To further ensure that the regulator doesn’t sink output current, (even with a ground signal applied to its Inhibit), the input voltage must always be greater than the applied pre-bias source. This condition must exist throughout the power-up sequence 3. A pre-bias startup condition occurs as a result of an external voltage being present at the output of a power module prior to its output becoming active. This often occurs in complex digital systems when current from another power source is backfed through a dual-supply logic component, such as an FPGA or ASIC. Another path might be via clamp diodes, sometimes used as part of a dual-supply power-up sequencing arrangement. A prebias can cause problems with power modules that incorporate synchronous rectifiers. This is because under most operating conditions, such modules can sink as well as source output current. The PTH12000x series of modules incorporate synchronous rectifiers, but will not sink current during startup, or whenever the Inhibit pin is held low. Startup includes an initial delay (approx. 8 - 15 ms), followed by the rise of the output voltage under the control of the module’s internal soft-start mechanism; see Figure 3-1. The soft-start period is complete when the output begins rising above the pre-bias voltage. Once it is complete the module functions as normal, and will sink current if a voltage higher than the nominal regulation value is applied to its output. Note: If a pre-bias condition is not present, the soft-start period will be complete when the output voltage has risen to either the set-point voltage. Demonstration Circuit The circuit shown in Figure 3-4 is a demonstrates the pre-bias startup feature. Figure 3-5 shows the startup waveforms. The initial rise in Vo 2 is the pre-bias voltage, which is passed from the VCCIO to the VCORE voltage rail through the ASIC. Note that the output current from the PTH12000L module (Io2) is negligible until its output voltage rises above the applied pre-bias. Conditions for Pre-Bias Holdoff In order for the module to allow an output pre-bias voltage to exist (and not sink current), certain conditions must be maintained. The module holds off a pre-bias voltage when Figure 3–4; Application Circuit Demonstrating Pre-Bias Startup 10 9 VIN = 12 V 2 5 8 Up Dn Track Sense PTH12020W VIN Inhibit Adjust GND 3 7 1 VO 2 R3 11k0 PTH12000L VIN VO 5 Vo2 = 1.8 V + 8 Inh VCC 7 2 1 3 3 SENSE RESET 5 TL7702B REF RESET 6 CT C5 0.1 µF C6 0.68 µF 4 GND Adj 1 Io2 4 R2 130 RESIN 330 µF VCCIO VCORE + C3 + C4 330 µF GND R4 100k 330 µF R1 2k 330 µF Vo1 = 3.3 V +C 2 4 + C1 6 ASIC R5 10k0 For technical support and further information visit http://power.ti.com Application Notes PTH12000 Series Figure 3–5; Pre-Bias Startup Waveforms Vo 1 (1 V/Div) Vo 2 (1 V/Div) Hold-off Period Io 2 (2 A/Div) HORIZ SCALE: 5 ms/Div Notes 1.
