Description: High Efficiency Synchronous Boost Converter

Features

* Input voltage range: 1.8V to 4.8V
* Fixed 5V or adjustable output
* Output current: up to 1.5A (PVIN = 3.3V, VOUT = 5V)
* High efficiency: up to 96%
* 35µA quiescent current maximizes light-load efficiency
* True input-output disconnect when disabled

Applications

* The device provides a power supply solution for products using dual-cell or three-cell alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery. This device is capable of delivering an output current of 1.5A with PVIN = 3.3V and VOUT = 5V. The use of a synchronous rectifier maximizes effici
