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.
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
