SY7069ADC

Silergy Corp · Battery Management · TSOT-23-6

SY7069ADC from Silergy Corp, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 FB input Output feedback pin. Connect to the center tap of an external resistor divider from VOUT to GND to program the output voltage: VOUT = 1.2V x (1 + RH/RL). Internal reference is 1.2V (typ).
2 IN power_in Signal input pin (2.5V to 5.5V). Decouple this pin to GND with at least 1uF ceramic capacitor for noise immunity. Also serves as one side of the boost inductor connection.
3 GND power_in Ground pin. Return for the low-side main NMOS switch and all internal circuitry.
4 OUT power_out Boost converter output pin (2.5V to 5.5V). Decouple to GND with at least 22uF ceramic capacitor (X5R or better, >=10V rating). Also feeds the synchronous PMOS to enable load-disconnect and auto-bypass modes. OVP triggers at 6.0V.
5 LX passive Inductor switching node. Connect an inductor (typ 1.5uH) between IN and LX. Internal main NMOS (RDS(ON) ~50mΩ) switches this node to GND; synchronous PMOS (RDS(ON) ~90mΩ) routes to OUT. Keep LX PCB area minimized for noise immunity.
6 EN input Enable pin. Pull high (>1.2V) to turn on the converter; pull low (<0.4V) to shut down (shutdown current <1uA). Do not leave floating.
