Pinout

Pin Name Type Function
1 UVLO input UVLO is the input to the Standby and UVLO comparators, where a resistor divider from VIN to ground sets the enable voltage, hysteresis comes from a 5 µA pull-down source, and an external pull-down can disable the controller.
2 FLT bidirectional FLT is the input to a window comparator with upper and lower fault thresholds, and it sources a precision current for an NTC to ground for over-temperature protection, with the upper threshold usable for output over-voltage sensing.
3 SS passive SS sets the soft-start ramp of the peak current limit using an internal 15 µA current source and an external capacitor to ground, with typical values of 10 nF to 100 nF.
4 RT passive RT sets the oscillator frequency and requires a resistor to ground placed close to the IC, with typical values of 10 kΩ to 100 kΩ.
5 COMP passive COMP provides the compensated error voltage for the PWM and skip comparators and has an internal 5 kΩ pull-up that can bias an opto-coupler transistor.
6 CS input CS is the current sense input for the PWM and current limit comparators, held low for 60 ns after DRV goes high to blank leading-edge spikes, and an external low-pass filter is recommended.
7 GND power_in GND is the controller ground.
8 DRV output DRV is a high-current output that drives the external MOSFET gate, with source capability of 1 A and sink capability of 2.8 A.
9 VCC power_in VCC provides bias to the controller and should have an external decoupling capacitor to ground in the range of 1 to 10 µF; supply voltage is 9 to 20 V recommended with a 30 V absolute maximum.
10 VIN power_in VIN is the input to the high-voltage startup regulator, which can source more than 15 mA to temporarily bias VCC during startup, with VIN limited to 120 V maximum for MSOP10.
