UC3842BD1013TR ST AC-DC Controllers

The UC3842BD1013TR is a fixed frequency current-mode PWM controller optimized for off-line and DC-DC converter applications in an 8-pin SOIC package. For selection, verify supply from 10V to 30V, UVLO thresholds of 16V (on) and 10V (off), 48% max duty cycle, 1A totem pole output, and operating temperature from -40°C to +150°C. Features include trimmed oscillator for precise frequency control up to 500kHz, low start-up current, and automatic feed-forward compensation. Ideal for off-line flyback converters, AC-DC adapters, battery chargers, and switching power supplies. In stock at HL Electronics – request a quote for fast delivery.
