SGM6603

90% Efficient Synchronous

Step-Up Converter with 1.1A 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 400mA from a

3.3V rail or a Li-Ion battery.

● 90% Efficient Synchronous Boost Converter

● Device Quiescent Current: 30µA (TYP)

● Less than 1μA Shutdown Current

● Input Voltage Range: 0.9V to 5.5V

● 3.3V and 5.0V Fixed Output Voltages

● Adjustable Output Voltage Up to 5.5V

● Output Voltage Clamping: 6V

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 into a compact space.

● Power-Save Mode for Improved Efficiency at Low

Output Power

● Load Disconnect During Shutdown

● Over-Temperature Protection

For light load current, the SGM6603 enters into the

power-save 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 V_OUTto go to zero volt during shutdown without

drawing any current from the input source.

● Available in Green SOT-23-6 Package

● -40℃ to +85℃ Operating Temperature Range

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 those

of SGM6603-3.3/SGM6603-5.0 are fixed internally on

the chip. The device is available in SOT-23-6 package.

It operates over an ambient temperature range of -40℃
