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.
The UCCx9411 family is designed to accommodate demanding applications such as pagers and cell phones that require high efficiency over a wide operating range of several milliwatts to a couple of hundred milli-watts.Ω
