PWM Voltage Mode Controller - ON Semiconductor
Description
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.
