Infineon to sell 5th gen CoolSET quasi-resonant fly-back controller in May

Infineon to sell 5th gen CoolSET quasi-resonant fly-back controller in May

The ICs are especially designed for AC/DC switch mode power supplies in a great variety of applications such as aux power for home appliances, server, and industrial SMPS. The latest 700 V and 800 V CoolMOS P7 families are integrated together with a fifth generation controller into a single package. The newly implemented cascode configuration for the high voltage MOSFET in combination with the internal current regulator provides fast startup. Light load performance is optimized through an Active Burst Mode (ABM) with selectable entry/exit thresholds. The design of the device incorporates new algorithms to minimize the switching frequency spread between different line conditions and simplify EMI filter design. Device protection includes input over-voltage protection, brown in/out, pin short to ground, and over-temperature protection with hysteresis. All protection features ...
