DESCRIPTION

The UCCx9411 family of low-input voltage, single-inductor-boost converters is optimized to operate from a single

or dual alkaline cell, and steps up to a 3.3 V, 5 V, or adjustable output at 200 mW. The UCCx9411 family also

provides an auxiliary 7 V output, primarily for the gate-drive supply, which can be used for applications requiring

an auxiliary output, such as 5 V, by linear regulating. The primary output starts up under full load at input

voltages typically as low as 0.8 V with a ensured max of 1 V, and operates down to 0.5 V once the converter is

operating, thereby maximizing battery usage.
