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.
Features
45 kHz, 65 kHz, 77 kHz
7% Frequency Accuracy Over the Whole Temp Range
Extended VCC Working Range 8.6 V to 16 V
Programmable Stand–by Burst Duty Cycle
Stand–by Mode Selection from the Secondary Side of the SMPS
5 mA VHV Start–up Current Source
Device Inhibition Through Start–up Current Source Reduction
Typical Applications
Energy Management in Set Top Box
Opto Feed–back Offline SMPS
SMPS Using a Secondary Reconfiguration for the Stand–by Mode
Ability to Adapt the MOSFET Gate Drive
All General Purpose Fly–back SMPS
