SGM6605

90% Efficient Synchronous

Step-Up Converter with 1.1A Switch

GENERAL DESCRIPTION

FEATURES

The SGM6605 is a constant frequency, current mode,

synchronous step-up switching regulator. It can 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: 2.7V to 5.5V

● 5.0V Fixed Output Voltage

High switching frequency minimizes the sizes of

inductor and capacitor. Integrated power MOSFETs

and internal compensation make the SGM6605 simple

to use and fit the total solution into a compact space.

● Adjustable Output Voltage Up to 5.5V

● Output Voltage Clamping: 6V

● Power-Save Mode for Improved Efficiency at Low

Output Power

For light load current, the SGM6605 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

SGM6605 provides true output disconnect and this

allows V_OUTto go to zero volts during shutdown without

drawing any current from the input source. The

SGM6605 supports 1.8V logic for control.

● Load Disconnect During Shutdown

● 1.8V Logic on EN Pin for Control

● Low Reverse Leakage Current when V_OUT> V_IN

● Over-Temperature Protection

● Available in Green SOT-23-6 Package

● -40℃ to +85℃ Operating Temperature Range

APPLICATIONS

The output voltage of SGM6605-ADJ can be

programmed by an external resistor divider, and that of

SGM6605-5.0 is fixed internally on the chip. The device

is available in the Green SOT-23-6 package. It

operates over an ambient temperature range of -40℃
