Microchip Technology MIC33153
The MIC33153 is a high-efficiency 4 MHz 1.2A synchronous buck regulator with an internal inductor, HyperLight Load® mode, Power Good (PG) output indicator, and programmable soft-start. The MIC33153 is designed so that only two external capacitors as small as 2.2 μF are needed for stability. This gives the MIC33153 the ease of use of an LDO with the efficiency of a HyperLight Load® DC converter.| Part No. | MIC33153 |
