The UTC UC3844/3845 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 UC3844 and UC3845 are the under-voltage lockout thresholds.
The UC3844 ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC3845 has UVLO thresholds of 8.4V(ON) and 7.6V(OFF) for lower voltage applications.
