(tpmic?) family. it is a dual voltage doubling charge pump that provides a regulated output voltage. it operates with an input voltage range of 2.7 to 5.0 volts. the device can deliver a constant 200ma output load current and up to 500ma of pulsed current. the 500ma peak current capability of the aat3112 makes it ideal for white led flash applications. a low external parts count (two 1 f flying capacitors and two small capacitors at v in and v out ) makes the aat3112 ide- ally suited for small battery-powered applications. the aat3112 has a thermal management system to pro- tect the device in the event of a short-circuit condition at the output pin. built-in soft-start circuitry prevents excessive inrush current during start-up. a high charge pump switching frequency enables the use of very small external capacitors. a low current shutdown feature dis- connects the load from v in and reduces quiescent current to less than 1 a. the aat3112 is available in a pb-free 16-pin 3x3mm qfn package and is rated over the -40c to +85c temperature range. fe a t u r e s input voltage range: ? aat3112-5.0: 2.7v to 5.0v ? aat3112-4.5: 2.7v to 4.5v up to 500ma peak output current 200ma continuous output current i q <1 a in shutdown regulated 4.5v or 5.0v output 26 a of quiescent current small application circuit automatic soft start no inductors short-circuit/over-temperature protection 16-pin 3x3mm qfn package temperature range: -40c to +85c applica t ion s general-purpose high-current boost supply white led backlighting white led photo flash typica l applica t ion aat3112 c1 + c1 - c2 + c2 - c1 = 1 f c2 = 1 f en1en2 enable light enable flash d1 d2 d3 d4 vout1vout2 vin c out r b gnd c in v in downloaded from: http:///
