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; just three small ceramic capacitors are needed. This makes the AAT3119 ideally suited for small battery-powered applications. This device operates from a fixed high frequency 1.2MHz oscillator which enables the use of very small external capacitors, one 1µF flying capacitor, and two 1µF bypass capacitors at IN and OUT. The AAT3119 has a thermal management system to protect the device in the event of a short-circuit condition at the output pin. Built-in soft-start circuitry prevents excessive inrush current from the source supply during startup. A low-current shutdown feature disconnects the load from V IN and reduces quiescent current to less than 1.0µA when the device is disabled. The AAT3119 is available in an 8-pin SC70JW package and is rated over the -40°C to +85°C temperature range.
