## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SENSE | input | Current-sense comparator input that must be Kelvin-connected to the positive terminal of the current-sense resistor in the source of the bottom MOSFET, with the resistor's negative terminal returned to the ground plane close to the chip; the SENSE absolute maximum range is -0.3V to 0.3V. |
| 2 | GND | power_in | Ground pin that must be tied directly to the ground plane. |
| 3 | GATE | output | Drives the gate of the external N-channel MOSFET with a voltage swing from ground to an internal 8V supply, and no positive or negative voltage source may be applied to it (absolute maximum range -0.3V to 10V). |
| 4 | RFB | input | Input for the external feedback resistor, connected from this pin to the transformer primary SW node, where the RFB current is regulated at 100µA (97.5µA to 102.5µA) and no voltage may be forced on this pin (RFB current rating -2mA to 200µA). |
| 5 | VIN | power_in | Input supply that powers the internal circuitry and sets the feedback reference, with an operating range of 4.5V to 60V (absolute maximum -0.3V to 60V) and to be locally bypassed to ground with a ceramic capacitor. |
| 6 | EN/UVLO | input | Enable and undervoltage-lockout pin that shuts the device down when pulled below 0.2V, has an accurate 1.228V enable threshold, supports a resistor-divider VIN UVLO with a 2.5µA hysteresis current, and must be tied directly to VIN if unused (absolute maximum -0.3V to VIN). |
