UC2843A Overview
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 suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC2843A has UVLO thresholds of...
