Microchip MIC33153-SYHJ-TR

Неизолированный модуль PoL2.7V5.5V3.3V1.2A93%

Overview

The MIC33153-SYHJ-TR is a high-efficiency 4MHz 1.2A synchronous buck regulator with an internal inductor, HyperLight Load® mode, Power Good (PG) output indicator, and programmable soft start. HyperLight Load® provides very high efficiency at light loads and ultra-fast transient response which makes the MIC33153-SYHJ-TR perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is very low output ripple voltage throughout the entire load range with the use of small output capacitors.The MIC33153-SYHJ-TR is designed so that only two external capacitors as small as 2.2 µF are needed for stability. This gives the MIC33153-SYHJ-TR the ease of use of an LDO with the efficiency of a HyperLight Load® DC converter. The MIC33153-SYHJ-TR achieves efficiency in HyperLight Load® mode as high as 85% at 1mA, with a very low quiescent current of 22µA. At higher loads, the MIC33153-SYHJ-TR provides a constant switching frequency up to 4MHz.The MIC33153-SYHJ-TR is available in 14-pin 3.0mm x 3.5mm package with an operating junction temperature range from -40°C to +125°C.
