概要

5th generation quasi-resonant CoolSET™ with integrated 800V CoolMOS™ SJ MOSFET in SMD package

Infineon’s 5^th generation of quasi-resonant CoolSET™ devices offers high performance and a comprehensive suite of protection. It integrates a flyback controller with a valley-switching scheme and an 800V CoolMOS™ P7 superjunction MOSFET in single DSO-12 package.

特長

Novel quasi-resonant switching scheme
Rapid and adjustable start-up with configuration
2-level selectable active burst-mode level
Built-in digital soft-start
Cycle-by-cycle peak current limitation
Digital frequency reduction with decreasing load for higher efficiency
Adjustable line input over-voltage and brown IN/OUT protection
V_CC pin short to ground protection
OLP, output short, output over-voltage, OTP with hysteresis and V_CC over/under voltage protection
Auto-restart for all protection features

利点

High efficiency thanks to the CoolMOS™ P7 SJ MOSFET family and the quasi-resonant switching scheme
Auto-restart recovery scheme to minimize interruption to system operation
Extensive protection coverage to increase system robustness
Rapid start-up performance with cascode configuration
