Quality Control: Learn More
The Microchip Technology MIC38HC44-1BM-TR is a high-performance, fixed-frequency current-mode PWM controller designed for offline switching power supplies. This component supports multiple topologies including Boost, Buck, Flyback, and Forward configurations, operating at a switching frequency of up to 500kHz. Featuring internal power MOSFETs, it simplifies design and reduces component count. The controller operates within a supply voltage range of 9V to 20V, with a startup voltage of 14.5V. Its 50% duty cycle capability and frequency control are critical for precise power regulation. The MIC38HC44-1BM-TR is housed in a 14-SOIC (0.154", 3.90mm Width) surface mount package, suitable for demanding industrial applications. The operating temperature range is -40°C to 150°C (TJ). This device is commonly utilized in industrial power supplies and consumer electronics.
