OB2004AMP

OB(On-Bright Elec) · AC-DC Controllers & Regulators · SOT-23-6

OB2004AMP from OB(On-Bright Elec), in a SOT-23-6. 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 pin; recommended VDD supply range is 5V to 7.5V, absolute maximum -0.6V to 8V, with UVLO entry at 4.6V typical and exit at 4.4V typical.
2 GND power_in Ground pin.
3 GATE output Driver output for the external N-channel SR MOSFET with 3A sink and 2A source typical capability, absolute maximum -0.6V to 8V.
4 VD input Connected to the drain of the external N-channel MOSFET (through resistor Rd) for Vds sensing, with absolute maximum rating of -2.5V to 85V.
5 RT passive Minimum on-time control pin where a resistor is connected from this pin to GND, with reference voltage of 1V typical and absolute maximum -0.6V to 7V.
6 VIN power_in System output voltage detection pin, with absolute maximum rating of -0.6V to 24V and SR disabled when VIN is below 2.5V typical.
