TPOWER · LED Drivers · ESOP-8L

TP8525 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 GND power_in Chip ground reference for the device.
2 VDD power_in Supply input with an internal 5.6 V zener clamp; the VDD-to-GND absolute maximum is -0.3 to +6 V, so a supply dropping resistor is required when the input voltage exceeds 5.6 V.
3 NC unconnected No internal connection.
4 SW output Drain of the internal power MOSFET; the SW-to-GND absolute maximum is -0.3 to +100 V.
5 CS input Output current sense pin; the LED average-current sense resistor is connected between CS and GND, with the internal reference at 200 mV for 100% brightness and 100 mV for 50% brightness.
6 MODE input High/low brightness mode select input (high = 50%, low = 100%); in high/low dimming applications it needs a 100 nF filter capacitor to GND, and it must not float, so it should be tied to VDD or GND when unused.
7 DIM input Analog dimming signal input with a dimming voltage range of 0.3 to 1.5 V, where the analog dimming turns off at 0.15 V and turns on at 0.2 V.
8 EN input Chip enable and PWM dimming signal input (high at 2.0 V minimum, low at 0.5 V maximum); a 10 to 100 nF filter capacitor to GND is required when dimming.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
