AIC1652GSTR

AIC(Analog Integrations) · DC-DC Converters · SOP-8

AIC1652GSTR from AIC(Analog Integrations), in a SOP-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 VIN power_in Input supply voltage pin, operating range 2.4V to 7V (absolute maximum 7V).
2 VREF power_out 1.22V reference output, bypass with a 0.047µF capacitor to GND; sourcing capability guaranteed greater than 250µA.
3 SHDN input Logic input to shut down the chip: >1.5V is normal operation, GND is shutdown (DLOW and DHI go high in shutdown); maximum 7V.
4 FB input Feedback signal input sensing ground; resistor R1 to VOUT and R2 to VREF set VOUT = -(R1/R2) x VREF.
5 GND power_in Power ground.
6 DLOW output Driver sinking output; with an external PNP transistor, connect resistor RB from this pin to DHI to optimize efficiency.
7 DHI output Driver sourcing output, connects to the base of the external PNP bipolar transistor.
8 CL input Current-limit input that clamps the switch peak current to prevent over-current damage to the external switch (threshold 70mV typical).
