SGM6603
90% Efficient Synchronous Boost Converter with 1.1A Switch
90% Efficient Synchronous Boost Converter with 1.1A Switch
GENERAL DESCRIPTION

The SGM6603 is a constant frequency, current mode, synchronous boost switching regulator. The input voltage can accept the voltage at a range from 0.9V to 5.5V. And the output voltage is adjustable with a peak of 5.5V. This device also has the 3.3V and 5.0V fixed output versions.

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.

The SGM6603 enters the power-save mode at light loads to maintain high efficiency. Anti-ringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode. The SGM6603 provides true output disconnection, allowing VOUT to go to 0V during shutdown without drawing any current from the input source.

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 a Green SOT-23-6 package. It operates over an ambient temperature range of -40 to +85.
