www.DataSheet4U.com CS51220 Feed Forward Voltage Mode PWM Controller with Programmable Synchronization CS51220 is a single output PWM Controller with switching frequency up to 500 kHz.

The feed forward voltage mode control provides excellent line regulation for wide input range.

This PWM controller has a synchronization output allowing programmable phase delay.

For overcurrent protection, the “soft hiccup” technique effectively limits the output current with maximum flexibility.

In addition, th
