TP8816B

TPOWER · LED Drivers · ESOP-8L

TP8816B from TPOWER, in a ESOP-8L. 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	S	passive	Source of the internal power MOSFET, which the datasheet rates for a 100 V drain-source breakdown (VBR_DSS) and an on-resistance of 100 mΩ for the TP8816B.
2	CS	input	Output current sense pin; the LED average-current sense resistor is connected between CS and GND, and the sense threshold is 200 mV at 100% brightness or 100 mV at 50% brightness, with CS and S rated -0.3 V to +6 V to GND.
3	GND	power_in	Chip ground, rated -0.3 V to +8 V relative to VDD and -0.3 V to +9 V relative to MODE per the absolute maximum ratings.
4	MODE	input	Brightness mode input: a high level (≥2.5 V) selects 50% output and a low level (≤2 V) selects 100% output, with an internal 80 kΩ pull-down, a clamp of 8.7 V, and an absolute maximum of -0.3 V to +9 V to GND.
5	NC	unconnected	No internal connection; the datasheet says this pin is left floating.
6	SW	output	Drain of the internal power MOSFET and the switching node of the buck converter, rated up to 100 V to GND; pin 6 and pin 7 are both SW and should be tied together.
7	SW	output	Drain of the internal power MOSFET and the switching node of the buck converter, rated up to 100 V to GND; pin 7 and pin 6 are both SW and should be tied together.
8	VDD	power_in	Supply input with an internal 7.5 V shunt regulator clamp; undervoltage lockout releases at 4.75 V rising with 4.0 V falling, and VDD to GND is rated -0.3 V to +8 V, with a bypass capacitor required close to the VDD and GND pins.
9	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
