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.

  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: ob2004amp-etched.step / ob2004amp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ob2004amp.step / ob2004amp.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: OB(On-Bright Elec) datasheet (11 pp, sha256 cce873112d63be8d, retrieved 2026-11-02, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
