AP3843CMTR-E1 DIODES DC-DC Controllers

The AP3843CMTR-E1 is a current-mode PWM controller from Diodes Incorporated in SOIC-8 surface-mount package, designed for DC-DC converter applications with UVLO thresholds of 8.5V (turn-on) and 7.6V (turn-off) . For selection, verify maximum duty cycle approaching 100%, trimmed oscillator for precise frequency control up to 500kHz, high-current totem pole output (1A peak) for driving MOSFETs, low start-up current (<0.5mA), current limiting with cycle-by-cycle control, and operating temperature from -40°C to +85°C . Features include automatic feed-forward compensation, pulse-by-pulse current limiting, internally trimmed bandgap reference, and UVLO with hysteresis. Ideal for DC-DC converters (buck, boost, flyback, forward), battery-powered equipment, automotive DC-DC converters, LED drivers, and any low-to-mid power conversion requiring current-mode PWM control.
