TOP414G [Power Integrations]

Low cost replacement for discrete switchers with up to 15 fewer components, increasing reliability and enabling smaller/lighter solutions under 12 mm height. Over 80% efficiency in flyback topology with built-in start-up, current limit, low-capacitance MOSFET, and CMOS controller consuming only 7 mW. Simplifies design with integrated PWM controller and high-power MOSFET, requiring only one external capacitor. Features system-level fault protection including auto-restart, cycle-by-cycle current limiting, and thermal shutdown. Highly versatile for Buck, Boost, Flyback, or Forward topologies, supporting continuous/discontinuous mode and operation down to 16 V DC input.
