Description

The InnoSwitch™3-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.
