Power Integrations InnoMux-2 ZVS Flyback Switcher ICs

Power Integrations InnoMux-2 Zero Voltage Switching (ZVS) Flyback Switcher ICs consolidate AC-DC and downstream DC-DC conversion stages into a single chip, providing up to three independently regulated outputs. The InnoMux-2 IC family offers up to 90W output power with better than ±3% accurate regulation across the full input line, temperature, load, and differential current-step conditions. The modules also feature total power system efficiency above 90% and manage light-load power delivery, avoiding the need for pre-load resistors and reducing no-load consumption to <30mW. The low no-load consumption conserves power for necessary functionality in applications subjected to the 300mW allowance for standby usage under EuP regulations.

Power Integrations InnoMux-2 ZVS Flyback Switcher ICs feature thermally efficient InSOP™24 and InSOP28 packages with PCB cooling, and no heatsink is required. Options include two and three constant voltage (CV) outputs. Optionally, one output may be dedicated to a constant current (CC) drive, which is ideal for powering LEDs in displays for high-speed charging of an internal battery.

InnoMux2-EP - up to three CV outputs or one CV and one CC output for a dimmable LED string
InnoMux2-BL - one CV and up to four CC outputs for dimmable LED strings in monitors or display panels
