Power Integrations expands Innoswitch range with lower power devices

Power Integrations has announced an expansion of its Innoswitch families of offline CV/CC flyback switcher ICs. The Inn3x78C devices incorporate a smaller “size 8” 750V PowiGaN transistor, enabling power supplies that deliver between 27W and 55W without heatsinks. The ICs are housed in the same InSOP-24D package as larger members of the GaN-based Innoswitch 3 ...
