UNISONIC TECHNOLOGIES CO., LTD UC3842B/3843B LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE CURRENT MODE CONTROLLERS  DESCRIPTION The UTC UC3842B/3843B are specifically designed for off-line and dc-to-dc converter applications offering the designer a cost-effective solution with minimal external components. The UC3842B has UVLO thresholds 16V (on) and 10V(off), ideally suited for off-line converters. The UC3843B is tailored for lower voltage applications having UVLO thresholds of 8.4V(on) and 7.6V(off).  FEATURES * Trimmed oscillator for precise frequency control * Oscillator frequency guaranteed at 250kHz * Current mode operation to 500kHz * Automatic feed forward compensation * Latching PWM for cycle-by-cycle current limiting * Internally trimmed reference with undervoltage lockout * High current totem pole output * Undervoltage lockout with hysteresis * Low startup and operating current  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UC3842BL-D08-T UC3842BP-D08-T UC3842BL-S08-R UC3842BP-S08-R UC3843BL-D08-T UC3843BP-D08-T UC3843BL-S08-R UC3843BP-S08-R www.unisonic.com.tw Copyright © 2019 Unisonic Technologies Co., Ltd Package Packing DIP-8 SOP-8 DIP-8 SOP-8 Tube Tape Reel Tube Tape Reel 1 of 11 QW-R103-012.H PDF
