TD8112X

Shenzhen JingYang · DC-DC Converters · SOT-23-6L

TD8112X from Shenzhen JingYang, in a SOT-23-6L. 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 BS passive Bootstrap. A capacitor (typ. 22 nF) connected between SW and BS forms a floating supply that drives the internal high-side power switch. BS voltage rating is (Vsw-0.3) to (Vsw+5) V.
2 GND power_in Ground return for the IC. Should be tied to a large copper area for thermal dissipation and low-impedance return of the switching current.
3 FB input Adjustable output feedback input. Connect to the center tap of an external resistor divider from VOUT to GND. Regulated reference is 0.6 V typ. (0.588 to 0.612 V); absolute max -0.3 to 6 V.
4 EN input Enable input. Drive logic-high to enable the IC; drive logic-low to disable and enter micro-power shutdown mode (~5 uA). Absolute max -0.3 to 18 V.
5 IN power_in Power supply input, 4.0 V to 18 V. Bypass with a low-ESR ceramic capacitor (typ. 22 uF) placed close to the pin.
6 SW output Switching node. Internal high-side/low-side power MOSFETs connect here; drives the external inductor. Absolute max -0.3 V to (VIN+0.5) V. High-side/low-side RDS(on) typ. 90/70 mOhm.
