UC2844 Description
The UTC UC2844/2845 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 UC2844 and UC2845 are the maximum duty cycle ranges and under-voltage lockout thresholds. The UC2844 ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC2845 has...
