AAT3119 Overview
The AAT3119 is a general purpose high efficiency voltage regulated charge pump IC that can produce output current levels up to 150mA. As a voltage regulated output device, it may be used for general voltage boost applications or to power white, RGB, or flash type LEDs from a 2.7V to 5.5V input. The voltage doubling charge pump architecture of the AAT3119 provides for a low external part count;.
AAT3119 Key Features
- Peak Current up to 250mA Regulated Output Voltage 1.2MHz Switching Frequency Low Noise Constant Frequency Operation <1.0
- supply during startup. A low-current shutdown fea- ture disconnects the load from VIN and reduces
- quiescent current to less than 1.0μA when the
- device is disabled. The AAT3119 is available .. in a
- Pb-free, 8-pin SC70JW package and is rated over
- the -40°C to +85°C temperature range
