† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

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.
