Microchip Technology MIC45208 10A DC-to-DC Power Module
Microchip MIC45208 10A DC-to-DC Power Module is a synchronous step-down regulator module, featuring a unique adaptive ON-time control architecture. The module incorporates a DC-to-DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor, and an inductor in a single package; simplifying the design and layout process for the end-user. This highly-integrated solution expedites system design and improves product time-to-market. The internal MOSFETs and inductors are optimized to achieve high efficiency at a low output voltage. The fully-optimized design can deliver up to 10A current under a wide input voltage range of 4.5V to 26V, without requiring additional cooling.
