TPS6024x 170-µVrms Zero-Ripple Switched Capacitor Buck-Boost
Converter for VCO Supply
1 Features
3 Description
•
•
The TPS6024x devices are a family of switched
capacitor voltage converters, ideally suited for
voltage-controlled oscillator (VCO) and phase-locked
loop (PLL) applications that require low noise and
tight tolerances. Its dual-cap design uses four
ceramic capacitors to provide ultra-low output ripple
with high efficiency, while eliminating the need for
inefficient linear regulators.

2 Applications
•
The devices are thermally protected and currentlimited for reliable operation even under persisting
fault conditions. Normal quiescent current (ground pin
current) is only 250 µA, and typically 0.1 µA in
shutdown mode. The TPS6024x devices come in a
thin, 8-pin VSSOP package with a component height
of only 1.1 mm.

Typical Application Schematic
3.3 V
The TPS6024x devices operate down to 1.8 V,
supporting a 3.3-V, 2.7-V, 3-V output from two-cell,
nickel- or alkaline-based chemistries, whereas the
TPS60241 works with 2.7-V to 5.5-V input voltage
providing a 5-V output. The devices work equally well
for low EMI DC–DC step-up conversion without the
need for an inductor. The high switching frequency
(typical 160 kHz) promotes the use of small surfacemount capacitors, saving board space. The shutdown
mode of the converter conserves battery energy.

7 Detailed Description
7.1 Overview
The TPS6024x device is a fixed-frequency, dual-phase charge pump that provides 25 mA of continuous supply
current for low-noise applications such as VCOs used in mobile phones and wireless applications.
Low-noise operation results from using a proprietary dual-phase charge pump topology that relies on an
operational amplifier in the feedback loop to reduce ripple. During the first phase, C1 is charged to the supply
voltage. Pin C1+ is connected to VIN, and C1– is connected to GND. In the second phase, C1– is connected to the
output of the operational amplifier, and C1+ is connected to VOUT. The operational amplifier then adjusts its output
until the output VOUT delivers the correct voltage to make the resistor divided feedback point equal to the
reference voltage. During this second phase, C2 is charged to supply voltage. Terminal C2– is connected to GND,
and C2+ is connected to VIN. Phase one is then repeated with C2, now acting to provide charge to the output in
place of C1, which is connected to the supply. The dual-phase operation lowers the output ripple voltage
significantly compared to a standard single-phase charge pump. In addition, the linear feedback of the
operational amplifier eliminates the ripple during discharge of the output capacitor (COUT).

7.3 Feature Description
7.3.1 Thermal Shutdown
The TPS6024x device has a built-in thermal shutdown which turns off the power stage when the junction
temperature exceeds typical 160°C. When the junction temperature drops to typical 140°C, the device starts
switching again.
7.3.2 Current Limit
The TPS6024x device has a built-in overload protection which limits the output current.
7.4 Device Functional Modes
7.4.1 Start-up Procedure
The converter is enabled when EN is set from logic low to high. The start-up time to reach 90% of the nominal
output voltage is typically 0.5 ms at load currents lower than 10 mA and with an output capacitor of 1 µF.
Increasing the values of COUT delays the start-up time.
7.4.2 Shutdown
Driving EN low disables the converter. This disables the internal circuits and reduces input current to typically 0.1
µA. In this mode, the load is disconnected from the supply voltage. The device exits shutdown once EN is set to
a high level.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TPS6024x is a switched capacitor voltage converter for VCO and PLL applications providing low noise
conversion and tight tolerances. It supports regulated output voltages of 2.7 V, 3 V and 3.3 V from a 1.8-V to 5.5V input voltage range. The TPS60241 generates 5-V output voltage from an 2.7-V to 5.5-V input voltage range.

9 Power Supply Recommendations
The TPS6024x devices have no special requirements for the input power supply. The output current of the input
power supply must be rated according to the supply voltage, output voltage, and output current of the TPS6024x.
10 Layout
10.1 Layout Guidelines
To achieve optimal noise behavior, keep the power lines to the capacitors and load as short as possible. Use of
power planes is recommended.
10.2 Layout Examples
