Remote Sense This module has remote sense compensation feature. It can minimize the effects of resistance between module’s output and load in system layout and facilitates accurate voltage regulation at load terminals or other selected point. 1. The remote sense lines carries very little current and hence do not require a large cross-sectional area. 2. This module compensates for a maximum drop of 10% of the nominal output voltage. 3. If the unit is already trimmed up, the available remote sense compensation range should be correspondingly reduced. The total voltage increased by trim and remote sense should not exceed 10% of the nominal output voltage. 4. When using remote sense compensation, all the resistance, parasitic inductance and capacitance of the system are incorporated within the feedback loop of this module. It can make an effect on the module's compensation, affecting the stability and dynamic response. A 0.1uF ceramic capacitor can be connected at the point of load to de-couple noise on the sense wires. 5. Recommend the connection of remote sense compensation as below figure. There are a resistor RS+ (51.1 ohm) from Vo+ to Sense+ and a resistor RS- (51.1 ohm)) from Vo- to Sense- inside of this module. Vo+ RS+ Sense+ Load SenseRS- V o- 6. If not using remote sense compensation, please connect sense directly to output at module's pin, that is, connect sense+ to Vo+ and sense- to Vo- at module's pin, the shorter the better.

Over Current Protection The module is equipped with internal current-limiting circuitry in order to provide protection in a fault output overload condition. The module will be in latch off mode when the output current exceeds the current limit and restart by either cycling the input power or by toggling the on/off pin. Over Voltage Protection The output over-voltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over voltage protection threshold, the module will shutdown into latch off mode. The over-voltage latch can be reset by either cycling the input power or toggling the on/off signal for one second at least.

Signal Definitions Pin Name Pin Description Logic level inputs used to set the output voltage, refer to VID table. Connect VID0 thru VID1 pins to open-drain outputs with external pull-up resistors or to active-pull-up outputs. Valid logic low is -0.3V to 0.4V, valid logic high level is 0.8V to 5.3V. The IMON pin is the average channel-current sense output. This pin is used as a load current indicator to monitor the output load current. The voltage on the Imon pin = 900mV when Iout = 90A. Logic level input used to enable the converter when high. Positive remote sense. Negative remote sense. Output voltage Trim. A low input signal indicates the low power mode operation of the processor. The controller drops the number of active phases to single phase operation. A high input signal pulls the controller back to normal operation. PGOOD indicates that soft-start has completed and the output voltage is within the regulated range around VID setting.
