OB2362AMP from OB On Bright Elec, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the controller. Return path for VCC supply and all internal circuitry.
2 FB input Feedback input pin. The PWM duty cycle is determined by the voltage level into this pin and the current-sense signal at the CS pin. Open-loop threshold VTH_OLP = 4.4 V; input impedance ~30 kΩ; PWM input gain ΔVFB/ΔVCS = 3.5 V/V.
3 PRT bidirectional Multi-function protection pin. Connect an NTC resistor to ground for external OTP detection (VOTP ~1 V, IRT ~100 uA). A resistor from Vaux sets the adjustable output OVP trigger threshold (Ioutput_ovp ~180 uA) and provides transformer core demagnetization / valley detection. If both OTP and OVP are used, a diode is placed between the PRT pin and the NTC resistor.
4 CS input Current sense input. Senses primary MOSFET current via a sense resistor. Internal current-limit threshold VTH_OC ~0.45 V (zero duty cycle), OCP clamp VTH_OC_Clamp ~0.72 V, leading-edge blanking 300 ns.
5 VCC power_in Chip supply voltage. Recommended operating range 12 to 26 V. UVLO(ON) ~17 V (recovery), UVLO(OFF) ~7.3 V, VCC OVP threshold ~28 V. Startup current ~2 uA; operating current ~2.5 mA; burst current ~0.6 mA.
6 Gate output Totem-pole gate driver output for the external power MOSFET. Output clamp ~11 V, VOH ≥6 V @ 20 mA, VOL ≤1 V @ 5 mA, rise/fall ~100/30 ns into 1 nF.
