UC3843A Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD UC3842A/3843A LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS - DESCRIPTION The UTC UC3842A/3843A 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 UC3842A and UC3843A are the under-voltage lockout thresholds. The UC3842A ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC3843A has UVLO thresholds of 8.4V(ON) and 7.6V(OFF) for lower voltage applications. - Features - Operation output switching frequency up to 500 kHz - Automatic feed forward...
