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.
