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 k Hz - Automatic feed forward pensation - Latching PWM for cycle-by-cycle current limiting - High current totem pole output - Internally trimmed reference with under voltage lockout - UVLO with hysteresis - Low startup and operating current - ORDERING INFORMATION Ordering Number Lead Free Halogen Free UC3842AL-D08-T UC3842AP-D08-T UC3842AL-S08-R UC3842AP-S08-R UC3843AL-D08-T UC3843AP-D08-T UC3843AL-S08-R UC3843AP-S08-R Package DIP-8 SOP-8 DIP-8...
