OBGZ56COPA
OB On Bright Elec · AC-DC Controllers And Regulators · SOP-8
OBGZ56COPA from OB On Bright Elec, in a SOP-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 | FB | input | Voltage feedback input from the auxiliary winding through a resistor divider that reflects the output voltage; the internal reference Vref_fb is 2.475 V to 2.525 V (2.500 V typical), and the FB input voltage is rated -0.3 V to 7 V. |
| 2 | GND | power_in | Ground reference for the controller. |
| 3 | VDD | power_in | Power supply input with a recommended range of 5 V to 16 V and an absolute maximum of -0.3 V to 20 V; the UVLO thresholds are 13 V (exit) and 3.7 V (enter), and VDD over-voltage protection trips at 18 V typical. |
| 4 | CS | input | Current sense input from the external sense resistor Rs, which sets the constant-current point; the OCP threshold is 500 mV minimum to 555 mV maximum, and the CS input voltage is rated -0.3 V to 7 V. |
| 5 | C | power_out | High-voltage BJT collector pin, rated for 450 V collector-emitter (Vceo) and 750 V collector-base (Vcbo), with a collector current of 1.6 A. |
| 6 | C | power_out | High-voltage BJT collector pin, rated for 450 V collector-emitter (Vceo) and 750 V collector-base (Vcbo), with a collector current of 1.6 A. |
| 7 | C | power_out | High-voltage BJT collector pin, rated for 450 V collector-emitter (Vceo) and 750 V collector-base (Vcbo), with a collector current of 1.6 A. |
| 8 | C | power_out | High-voltage BJT collector pin, rated for 450 V collector-emitter (Vceo) and 750 V collector-base (Vcbo), with a collector current of 1.6 A. |
