SGM6013中文资料1.6MHz, 600mA Synchronous Step-Down Converter数据手册SGMICRO规格书

描述 Description

The SGM6013 is a 1.6MHz constant frequency, current mode, synchronous, step-down switching regulator. It can deliver 800mA load current from 2.5V to 5.5V input voltage, and the output voltage can be as low as 0.6V.

The high switching frequency minimizes the sizes of inductor and capacitor. Integrated power MOSFETs and internal compensation make the SGM6013 simple to use and fit the total solution in a compact space.

The SGM6013 can operate at a low dropout for the 100% duty cycle, which can conserve the battery life of portable devices. The synchronous architecture eliminates the external Schottky diode, and achieves over 90% of the power conversion efficiency. With low output ripple voltage at light load, the 30μA quiescent current and less than 1μA shutdown current make SGM6013 the ideal power supply solution for portable applications.

SGM6013 is available in both adjustable and fixed (1.2V, 1.8V, 3.3V) output voltage versions. It is available in Green TSOT-23-5 and TDFN-2×2-6L packages. It is rated over the -40℃ to +85℃ temperature range.
