Microchip Technology MIC23153
The MIC23153 is a high-efficiency 4 MHz 2A synchronous buck regulator with HyperLight Load® mode, Power Good (PG) output indicator, and programmable soft-start. The tiny 2.5 mm x 2.5 mm thin DFN package saves precious board space and requires only four external components. The MIC23153 is designed for use with a very small inductor, down to 0.47 µH, and an output capacitor as small as 2.2 µF that enables a total solution size, less than 1 mm in height.| Part No. | MIC23153 |
