At Electronica in Munich today, Power Integrations announced a family of digitally controllable, off-line constant-voltage constant-current zero voltage switching (CV CC ZVS) fly-back ICs for compact power adaptors. Called InnoSwitch4-Pro, they have integrated 750V GaN (gallium nitride) primary switches, handle up to 220W, and switch at up to 140kHz with planar transformers. 10mV/step and 30mA/step ...
