OB3398ETAP-H

OB On Bright Elec · LED Drivers · DIP-8

OB3398ETAP-H 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	GND	power_in	Ground reference pin for the device.
2	NC	unconnected	No connect; the datasheet lists this pin as not connected internally.
3	CS	input	Current sense input; the LED constant current is set externally by resistor Rs at this pin, and the CS input voltage is limited to -0.3 V to 7 V.
4	FB	input	Connected to a resistor divider from the primary or auxiliary winding to reflect the output voltage, with the FB input voltage limited to -0.3 V to 7 V.
5	VDD	power_in	Power supply pin with a recommended supply range of 12 V to 25 V and an absolute maximum range of -0.3 V to VDD_clamp.
6	Drain	output	Drain of the internal high-voltage power MOSFET, with drain voltage limited to -0.3 V to BVdss.
7	Drain	output	Drain of the internal high-voltage power MOSFET, with drain voltage limited to -0.3 V to BVdss.
8	Drain	output	Drain of the internal high-voltage power MOSFET, with drain voltage limited to -0.3 V to BVdss.
