The TOP252EG from Power Integrations is a TOPSwitch®-HX Flyback off-line switcher with an integrated power switch, rated for up to 21 W in isolated designs. It features a 700V breakdown rating, selectable 66kHz and 132kHz switching frequencies, and up to 78% duty cycle. Current limiting, over temperature, and over voltage protection ensure reliable operation. Housed in a 7-SSIP package with exposed pad and formed leads, it operates across a -40°C to 150°C junction temperature range.
- Integrated 700V switch reduces external component count for compact isolated Flyback designs.
- Selectable 66kHz/132kHz switching frequencies offer flexibility in transformer and EMI design trade-offs.
- Up to 78% duty cycle supports efficient power transfer up to 21 W.
- Current limiting, over temperature, and over voltage protection enhance system reliability.
- Wide -40°C to 150°C junction temperature range suits demanding thermal environments.
