Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CT | passive | Capacitor setting the shutdown delay time, charged by a 5µA current source with a 2.6V threshold. |
| 2 | OV | input | Over output voltage protection pin; the OV threshold is 2.25V typical with 10µA hysteresis current source, and the device latches up if the output exceeds the OVP high threshold. |
| 3 | UVLO | input | Two resistors connected from this pin to GND and the power supply set the start-up and shutdown level; the UVLO threshold is 1.25V typical. |
| 4 | EN | input | Enable pin with 2.5V minimum high threshold and 0.5V maximum low threshold; VEN=0 gives shutdown supply current of 1µA typical. |
| 5 | VIN | power_in | Input supply pin, which must be locally bypassed; input voltage range is 5V to 27V. |
| 6 | VCC | power_out | Bypass to GND with a ceramic capacitor; VCC is regulated to 10.0V typical for 11V≤VIN≤27V with a 35mA current limit. |
| 7 | OUT | output | Connect to the gate of the external MOSFET; the gate driver has 1A peak current capability. |
| 8 | GND | power_in | Ground. |
| 9 | FAULT | output | Drives an external MOSFET with the same logic phase as PWM, and is pulled to ground under OVP, UVLO, OTP, diode short circuit, or LED short circuit fault conditions. |
| 10 | RT | passive | External resistor from this pin to GND sets the operating frequency, which is adjustable from 100kHz to 1MHz; RT voltage is 1.25V typical. |
| 11 | CS | input | Senses switch current for current mode control and current limit; the current limit threshold is 0.5V typical (0.48V to 0.52V). |
| 12 | SC | passive | Slope compensation for current sense; a resistor between SC and GND programs the slope compensation. |
| 13 | SS/COMP | passive | External soft-start capacitor from this pin to GND, charged by an internal 20µA current source (16µA to 28µA range); also the output of the internal error amplifier for compensation. |
| 14 | FB | input | Voltage feedback pin with a 500mV reference (490mV to 510mV). |
| 15 | PWM | input | Can be connected to a current matched chip and receives an error signal used to shut down the system; PWM threshold is 2.5V minimum high and 0.5V maximum low. |
| 16 | FLAG | output | Fault condition output that goes logic low to shut down the power path when the output is in short circuit condition. |
