OB3396AP

OB(On-Bright Elec) · AC-DC Controllers & Regulators · DIP-8

OB3396AP 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 VDD power_in Power supply fed from the transformer auxiliary winding, with UVLO off at 15.2V typ and on at 9.4V typ, OVP at 27.5V typ and clamp at 28.5V typ.
2 COMP input Loop compensation pin, with absolute maximum voltage of -0.3 to 7V.
3 GND power_in Ground.
4 INV input Voltage feedback from the auxiliary winding via a resistor divider reflecting the output voltage, with absolute maximum of -0.3 to 7V.
5 CS input Current sense input, with 800mV typ over-current threshold and absolute maximum of -0.3 to 7V.
6 SOURCE passive Source of the internal HV MOSFET, where the external sense resistor Rs sets the constant-current point and output power.
7 DRAIN passive Drain of the internal HV MOSFET (600V min breakdown), internally connected to pin 8.
8 DRAIN passive Drain of the internal HV MOSFET (600V min breakdown), internally connected to pin 7.
