产品描述

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. High efficiency at low output current is achieved by optimizing switching and conduction losses with a low total quiescent current. At higher output current, the 0.5 synchronous rectifier along with continuous mode conduction provide high power efficiency. The wide input voltage range of the UCCx9411 family can accommodate other power sources such as NiCd and NiMH.

The UCCx9411 family also provides shutdown control. Packages available are the 8-pin SOIC (D) and 8-pin TSSOP (PW) to optimize board space.
