5.5V 1.4A Boost DC/DC Converter

The XC9147/48 series is a new synchronous boost converter optimised to provide high efficiencies under all load conditions.

Output currents of 750mA minimum can be achieved with only two low cost ceramic capacitors and an Inductor placed externally. The internal circuit can start operation from input voltages as low as 0.9V and once started will continue to operate even when VIN is as low as 0.65V.

This series also features an optional load disconnect function that prevents the battery charge from leaking to the output while the IC is not operating or an input bypass mode function to keep the connection between the input and output side during shutdown.

The XC9147/48 is available in an ultra-small USP-6C or in the industry standard SOT-89-5 package.
