NCP1566 Datasheet (ON Semiconductor) - Dual-Mode Active Clamp PWM Controller

NCP1566, Dual-Mode Active Clamp PWM Controller

Pin Number Name Function 1 RAMP PWM modulator ramp.

In voltage mode an external R *C circuit from Vin sets the PWM Ramp slope to implement feedforward.

In current mode control, the resistor of the external R *C circuit connects to REF for ramp compensation 2 SS Soft *

Highly Integrated Dual-Mode Active Clamp PWM Controller NCP1566 The NCP1566 is a highly integrated dual mode active clamp PWM controller targeting next generation high density, high performance and small to medium power level isolated dc dc converters for use in telecom and datacom industries.

It can be configured in either voltage mode control with input voltage feed forward or peak current mode control.

Peak current mode control may be im
