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.
