The InnoSwitch3-Pro series family of ICs dramatically simplifies the development and manufacturing of fully programmable, highly efficient power supplies, particularly those in compact enclosures. The universal I²C interface enables dynamic control of output voltage and current along with many configurable features. Telemetry provides reporting of programmed features and fault modes.

InnoSwitch3-Pro devices are ideal for AC/DC power supply applications where fine (10 mV, 50 mA) output voltage and current adjustment are necessary. Typical implementations comprise a system microprocessor or dedicated microcontroller with an I²C port that is used to configure, control and supervise operation of the power sub-system. The uVCC pin provides bias to the microprocessor in standalone implementations such as USB PD adapters and chargers.
