lingxingic · Charge Pumps · SOT-23-6

LX4004A from lingxingic, in a SOT-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 OUT power_out Regulated boosted voltage output, nominally 4.95 V (±3%) at up to 230 mA. Requires a low-ESR ceramic bypass capacitor of 2.2 uF or greater (typ. 2.2-10 uF) to GND for ripple suppression.
2 GND power_in Device ground reference for the charge pump, control logic, and output stage.
3 SD input Active-high shutdown/enable input. Drive high (to VDD) to enable the charge pump; drive low (to GND) to disable OUT and enter standby (shutdown current <1 uA). Absolute max range -0.3 V to +5.5 V.
4 CN passive Flying (bootstrap) capacitor negative terminal. Connect a low-ESR ceramic capacitor (≥2.2 uF, typ. 2.2-10 uF) between CP (pin 6) and CN (pin 4) for the charge-pump doubler operation.
5 VDD power_in Main power supply input, 2.7 V to 4.5 V operating range (absolute max +5.5 V). Bypass with a low-ESR ceramic capacitor of ≥2.2 uF (typ. 2.2-10 uF) to GND.
6 CP passive Flying (bootstrap) capacitor positive terminal. Paired with CN (pin 4) via a ≥2.2 uF low-ESR ceramic capacitor to transfer charge in the voltage-doubler switching operation (fOSC ≈ 380 kHz).
