NCP1209 Product Preview PWM Voltage Mode Controller
The NCP1209P series is an enhanced version of the MC44608P series. It is a high performance voltage mode controller designed for fly-back SMPS. These 2 series are pin to pin compatible. The device is a Power MOSFET driver offering a discrete approach (controller + discrete MOSFET) for building an offline SMPS. It features a very high efficiency stand-by management consisting in a fully controlled and adaptable Pulsed Mode operation working in conjunction with a secondary reconfiguration.
