SGM6605 Synchronous Boost Converter with 1.1A Switch
■The SGM6605 is a constant frequency, current mode, synchronous boost switching regulator. The input voltage can accept the voltage at a range from 2.7V to 5.5V. And the output voltage is adjustable with a peak of 5.2V. This device also has the 5.0V fixed output version.
■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.
■The SGM6605 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 SGM6605 provides true output disconnection, allowing allows V-OUT to go to zero volts during shutdown without drawing any current from the input source. The SGM6605 supports 1.8V logic for control.
■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 a Green SOT-23-6 package. It operates over an ambient temperature range of -40°C to +85°C.
