SGM6012-ADJYTN5G/TR

SGM6012 1.6MHz, 800mA Synchronous Step-Down Converter GENERAL DESCRIPTION FEATURES The SGM6012 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 output voltage can be as low as 0.6V. ● High Efficiency: Up to 95% ● 30μA Low Quiescent Current at Light Load ● 800mA Output Current ● Input Voltage Range: 2.5V to 5.5V ● 1.2V, 1.8V & 3.3V Fixed & Adjustable Output Voltages High switching frequency minimizes the sizes of inductor and capacitor. Integrated power MOSFETs and internal compensation make the SGM6012 simple to use and fit the total solution in a compact space. ● 0.6V Reference Voltage ● 1.6MHz Constant Switching Frequency ● Less than 1μA Shutdown Current ● 100% Duty Cycle for Lowest Dropout ● No External Power MOSFETs and Schottky Diode The SGM6012 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. The synchronous architecture eliminates the external Schottky diode, and achieves over 90% of the Required ● Excellent Line Regulation & Load Transient Response ● -40℃ to +85℃ Operating Temperature Range ● Available in Green TSOT-23-5 Package power conversion efficiency. Low output ripple voltage at light load, 30μA quiescent current and less than 1μA of shutdown current make SGM6012 the ideal power supply solution for portable applications. APPLICATIONS GPS MP3 Players SGM6012 is available in both adjustable and fixed (1.2V, Cellular, Smart Phones 1.8V, 3.3V) output voltage versions. It is in the Green TSOT-23-5 package. It is rated over the -40℃ to +85℃ Digital Book Readers temperature range.

SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
