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, this device includes such features as: soft start,
pulse
by
pulse current limit, programmable foldback current limit,
volt
second clamping, maximum duty cycle, overvoltage and
undervoltage protection, and synchronization input. The CS51220 is
available in 16 SO narrow surface mount package.
