SY8029AIC

Silergy Corp · DC-DC Converters · TSOT-23-8

SY8029AIC from Silergy Corp, in a TSOT-23-8. 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 FB1 input Feedback pin for output1; connect it to the center point of the output resistor divider to program VOUT1 = 0.6V*(1+RH1/RL1).
2 IN power_in Power input pin; decouple it to ground with at least 10uF ceramic capacitance. The input supply range is 2.5V to 5.5V.
3 LX1 output Inductor pin for output1; connect it to the switching node of the output1 inductor.
4 GND power_in Ground pins.
5 LX2 output Inductor pin for output2; connect it to the switching node of the output2 inductor.
6 EN2 input Enable pin for output2; do not leave it floating.
7 EN1 input Enable pin for output1; do not leave it floating.
8 FB2 input Feedback pin for output2; connect it to the center point of the output resistor divider to program VOUT2 = 0.6V*(1+RH2/RL2).
