EA9755

Everanalog IC design · LED Drivers · SOT-23-6

EA9755 from Everanalog IC design, 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 SW output Switch node pin: connect the inductor and diode here and minimize the trace area at this node to reduce EMI.
2 GND power_in Ground pin: connect directly to the local ground plane.
3 FB input Feedback pin with a 195mV reference voltage: connect the cathode of the lowest LED and the sense resistor here, with RFB=VFB/ILED.
4 EN input Enable and dimming pin: logic high enables the device and logic low forces shutdown, and an external 100Hz to 50kHz PWM signal with amplitude greater than 1.5V provides digital dimming.
5 OVP input Over voltage input that measures the output voltage for open circuit protection: connect it to the output at the top of the LED string.
6 VIN power_in Input supply pin that must be locally bypassed, with a recommended input voltage of 2.5V to 5.5V.
