This manual describes the software implementation including driver libraries used to control InnoSwitch4-Pro operations. Important aspects of this document are calculations for the values to be programmed for various configurations such as voltage, current, cable drop compensation, constant power, I²C command sequences to prevent any unexpected behaviors, device responses and code examples.

InnoSwitch4-Pro digitally controllable off-line CV/CC flyback switcher ICs feature a 750 V PowiGaN switch, active clamp drive and synchronous rectification. They pair with ClampZero active clamp ICs for ZVS or use stand-alone for quasi-resonant mode.
