Preliminary Datasheet SGM6603 90% Efficient Synchronous Step-Up Converter with 1A Switch GENERAL DESCRIPTION FEATURES The SGM6603 is a constant frequency, current mode, synchronous, step-up switching regulator. Its output currents can go as high as 75mA while using a single-cell alkaline, and discharge it down to 0.9V. It can also be used for generating 5V at 500mA from a 3.3V rail or a Li-ion battery. ● 90% Efficient Synchronous Boost Converter ● Device Quiescent Current: 30µA (TYP) ● ● ● ● ● ● Lower than 1µA in Shutdown Status Input Voltage Range: 0.9V to 5.5V 3.3V and 5.0V Fixed Output Voltages Output Voltage Clamping: 6V Adjustable Output Voltage Up to 5.5V Power-Save Mode Version Available for Improved Efficiency at Low Output Power ● Load Disconnect During Shutdown High switching frequency minimizes the sizes of inductor and capacitor. Integrated power MOSFETs and internal compensation make the SGM6603 simple to use and fit the total solution in a compact space. ● Over Temperature Protection ● Available in Green SOT-23-6 Package ● -40℃ to +85℃ Operating Temperature Range For light load current, the SGM6603 enters into the power saving mode to maintain high efficiency. Anti-ringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode. The SGM6603 provides true output disconnect and this allows VOUT to go to zero volts during shutdown without drawing any current from the input source. APPLICATIONS Single-Cell Li Battery Powered Products Portable Audio Players The output voltage of SGM6603-ADJ can be programmed by an external resistor divider, and that of SGM6603-3.3/SGM6603-5.0 are fixed internally on the chip. The device is available in SOT-23-6 package. It operated over an ambient temperature range of -40℃ to Cellular Phones Personal Medical Products +85℃.
