AP3844CMTR-E1 DIODES AC-DC Controllers

The AP3844CMTR-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 switching frequency up to 500kHz, maximum duty cycle of 50%, 1A totem pole output for driving MOSFETs, operating supply voltage range, current limiting with cycle-by-cycle control, overcurrent protection (OCP), secondary-side feedback, PWM modulation mode, and operating temperature from -40°C to +85°C. Features include trimmed oscillator for precise frequency control, low start-up current, automatic feed-forward compensation, and pulse-by-pulse current limiting. Ideal for DC-DC converters (buck, boost, flyback, forward), battery-powered equipment, LED drivers, industrial power supplies, and any low-to-mid power conversion requiring current-mode PWM control with 50% maximum duty cycle .
