UC1843B-D Overview
The UTC UC1842B-D/1843B-D 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 UC1842B-D and UC1843B-D are the under-voltage lockout thresholds. The UC1842B-D ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC1843B-D has UVLO...
