OB2263AP

OB On Bright Elec · AC-DC Controllers And Regulators · DIP-8

OB2263AP from OB On Bright Elec, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GATE output Totem-pole gate drive output for the power MOSFET, clamped to a maximum of 18V.
2 VDD power_in Chip DC power supply pin, operating range 10 to 30 V with UVLO on at 8.8 V and off at 14 V typical, and a 34 V clamp.
3 NC unconnected No connection.
4 SENSE input Current sense input pin connected to the MOSFET current sensing resistor node, with leading edge blanking and -0.3 to 7V input range.
5 RI input Internal oscillator frequency setting pin where a resistor to GND sets the PWM frequency (RI range 50 to 150 Kohm, 100 Kohm gives 65 KHz).
6 NC unconnected No connection.
7 FB input Feedback input pin that together with the SENSE pin input determines the PWM duty cycle, with -0.3 to 7V input range.
8 GND power_in Ground.
