UC1841
FEATURES
- All Control, Driving, Monitoring, and Protection Functions Included
DESCRIPTION
The UC1841 family of PWM controllers has been designed to increase the level of versatility while retaining all of the performance features of
- Low-current, Off-line Start Circuit
- Voltage Feed Forward or Current Mode Control the earlier UC1840 devices. While still optimized for highly-efficient bootstrapped primary-side operation in forward or flyback power converters, the UC1841 is equally adept in implementing both low and high voltage input DC to DC converters. Important performance features include a
- Guaranteed Duty Cycle Clamp low-current starting circuit, linear feed-forward for constant volt-second operation, and patibility with either voltage or current mode topologies.
- PWM Latch for Single Pulse per Period In addition to start-up and normal regulating PWM functions, these de-
- Pulse-by-Pulse Current Limiting Plus vices include built in protection from over-voltage,...
