简  介:High Efficiency 2X Charge Pump General Description 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 built-in soft-start circuitry which prevents excessive inrush current from the source supply during startup. A low-current shutdown feature 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.
