Programmable Off-Line PWM Controller
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 compatibility with either voltage or current mode topologies. ...
