UNISONIC TECHNOLOGIES CO., LTD UC3844/45 LINEAR INTEGRATED CIRCUIT HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS  DESCRIPTION The UTC UC3844/3845 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 UC3844 and UC3845 are the maximum duty cycle ranges and under-voltage lockout thresholds. The UC3844 ideally suited to off-line applications with UVLO thresholds of 16V(ON) and 10V(OFF), and UC3845 has UVLO thresholds of 8.5V(ON) and 7.6V(OFF) for lower voltage applications.  FEATURES * Operation output switching frequency up to 500 kHz * Automatic feed forward compensation * 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 UC3844L-D08-T UC3844G-D08-T UC3844G-S08-R UC3845L-D08-T UC3845G-D08-T UC3845G-S08-R www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd Package Packing DIP-8 SOP-8 DIP-8 SOP-8 Tube Tape Reel Tube Tape Reel 1 of 7 QW-R103-010.H PDF
