UC2842A - PWM CONTROLLERS

The UTC UC2842A/2843A are high performance fixed frequency current mode controllers that specifically designed for Off-Line and DC to DC converter applications with minimal external parts count. The differences between UC2842A and UC2843A are the under-voltage lockout thresholds. The UC2842A ideally.
