UC2844 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD UC2844/45 LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS - 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 UVLO thresholds of 8.5V(ON) and 7.6V(OFF) for lower voltage applications. - Features - Operation output switching frequency up to 500 kHz - Output...
