1A高效Buck变换器G5691RB1U

一般的描述
The G5691 provides complete control for a DC/DC converter optimized for high-performance microproc-essor applications. It is operated on current mode ar-chitecture for excellent line and load transient re-sponse. 1.5MHz operation frequency is allowing the use of small surface mount inductor and capacitor. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. The G5691 is a family of low-noise synchronous step-down DC/DC converters that is ideally suited for systems powered from a 1-cell Li-ion battery or from a 3-cell to 4-cell NiCd, NiMH, or alkaline battery. It can also be used to USB-Based power system.
