The TOP226YN is a 125W second generation 3-terminal Off-Line PWM Switch provides several enhancements over the first generation TOPSwitch family. Many significant circuit enhancements that reduce the sensitivity to board layout and line transients now make the design even easier. TOPSwitch incorporates all functions necessary for a switched mode control system into a three terminal monolithic IC are power MOSFET, PWM controller, high voltage start up circuit, loop compensation and fault protection circuitry.
Description: TOP226YN is a high performance off-line switcher integrated circuit with a power factor correction (PFC) controller and a high voltage power MOSFET. Features: High performance off-line PFC controller Low start-up current Internal start-up circuit Internal soft-start circuit Internal over-voltage protection Internal over-current protection Internal thermal shutdown Low standby power consumption Low operating frequency High efficiency Applications: AC/DC adapters Battery chargers Lighting ballasts Power supplies Uninterruptible power supplies (UPS) Motor drives Home appliances (For reference only)
