INNxx6xC − 650 V switch, INNxx7xC − 725 V switch, INNxx79C and development and manufacturing of ful y programmable, highly efficient INNxx70C − 750 V switch. power supplies, particularly those in compact enclosures. The universal I2C interface enables dynamic control of output voltage and current InnoSwitch3-Pro devices are ideal for AC/DC power supply applications along with many configurable features. Telemetry provides reporting where fine (10 mV, 50 mA) output voltage and current adjustment are of programmed features and fault modes. necessary. Typical implementations comprise a system microprocessor or dedicated microcontrol er with an I2C port that is used to configure, control and supervise operation of the power sub-system. The uVCC pin provides a bias supply for the microprocessor in stand-alone implemen- tations such as USB PD adapters and chargers. www.power.com July 2019 This Product is Covered by Patents and/or Pending Patent Applications.
