PI: InnoSwitch Family of ICs Enables High Power Density and Low Component Count for USB-C PD PPS Chargers

Xiaoge Wang, FAE engineer at Power Integrations, shared a wonderful speech entitled “InnoSwitch4-CZ and InnoSwitch3-PD IC Product Families: Achieving Highest Power Density and Lowest Component Count for USB-C PD PPS Chargers”. Launched in 2014, the InnoSwitch series ICs have shipped more than 1 billion units.

The Inno4-CZ secondary controller is the mastermind that precisely controls 3 switches: the secondary SR FET, the primary switch, and the clamp switch. The Inno4-CZ controls the turn-on and turn-off timing of each switch, ensuring maximum efficiency over varying input voltage and load conditions. When the SR FET is off, before the Inno4 asks the primary side to start switching, the HSD pin sends a signal to ClampZero to turn on the clamp switch, ensuring that all the energy in the inductor is transferred, and then turns on the primary switch. This will ensure true zero voltage switching every cycle.

InnoSwitch3-PD is a highly integrated USB-C PD + PPS power adapter solution, and is currently the only USB PD single-chip solution in the industry. It inherits the consistent excellent performance of the InnoSwitch3 series, with extremely high efficiency, low no-load power consumption, and complete protection; at the same time, it significantly simplifies the BOM – ideal for applications requiring ultra-thin and small form factor, easy mass production, single-sided PCB.
