SL2365A

Slkor SLKORMICRO Elec · AC-DC Controllers and Regulators · SOT-23-6

SL2365A from Slkor SLKORMICRO 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. All internal circuits and external component returns tie here.
2 Fb input Feedback pin, connected to optocoupler feedback. Voltage on FB is compared with the internal sawtooth ramp to control duty cycle (current-mode control). Open-loop voltage ~5.1 V; input impedance ~30 kΩ; OLP threshold 4.4 V typical.
3 Pro input Protection pin. Multi-function pin for programmable output OVP (upper bias resistor, threshold current ~180 µA during demag) and external OTP via NTC lower bias (VOTP ~1 V, IRT ~100 µA).
4 Cs input Current sense input. Senses primary MOSFET source current via external sense resistor for cycle-by-cycle OCP (VTH_OCP 0.72 V) and internal current-limit threshold (0.45 V typ at 0% duty). LEB ~300 ns.
5 Vdd power_in Supply voltage input. Recommended operating range 12-26 V; VTH_ON ~17 V, VTH_OFF ~7.3 V; UVLO and OVP (~28 V) protection built-in. Absolute max 28 V.
6 Gate output PWM gate driver output for the external primary power MOSFET. Totem-pole driver with 11 V clamp; VOH ≥ 6 V @ 20 mA, VOL ~1 V @ 5 mA; TR ~100 ns / TF ~30 ns into 1 nF.
