UC3842 HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER

The UC384xB family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include a trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lock out featuring start-up current less than 0.5mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit

UC3842B (UC3842B / UC3843B) HIGH PERFORMANCE CURRENT MODE CONTROLLERS

„  DESCRIPTION
The UTC UC3842B/3843Bare specifically designed for off-line and dc-to-dc converter applications offering the designer a cost-effective solution with minimal external components. The UC3842Bhas UVLO thresholds 16V (on) and 10V(off), ideally suited for off-line converters. The UC3843Bis tailored for lower voltage applications having UVLO thresholds of 8.4V(on) and 7.6V(off).
