DATA SHEET AAT3112 500mA High Efficiency Charge Pump for White LED Flash Applications General Description Features The AAT3112 is a member of Skyworks’ Total Power Management IC™ (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 1μF flying capacitors and two small capacitors at VIN and VOUT) makes the AAT3112 ideally suited for small battery-powered applications. • 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 • IQ <1μA in Shutdown • Regulated 4.5V or 5.0V Output • 26μA of Quiescent Current • Small Application Circuit • Automatic Soft Start • No Inductors • Short-Circuit/Over-Temperature Protection • 16-Pin 3x3mm QFN Package • Temperature Range: -40°C to +85°C The AAT3112 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 during start-up. A high charge pump switching frequency enables the use of very small external capacitors. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to less than 1μA. The AAT3112 is available in a Pb-free 16-pin 3x3mm QFN package and is rated over the -40°C to +85°C temperature range.

This device boosts an input voltage to a regulated output voltage. Regulation is achieved by sensing the output voltage through an internal resistor divider network. The AAT3112 requires only four external components: two 1.0μF ceramic capacitors for the charge pump (C1 and C2), one 10μF ceramic capacitor for CIN, and one 10μF ceramic capacitor for COUT. 12 The AAT3112 is designed to deliver 200mA of continuous current and up to 500mA of pulsed current. Each charge pump engine has an independent enable pin to extend battery life. The charge pump switching frequency is approximately 750kHz, enabling the use of small external flying capacitors. The AAT3112 has complete output short-circuit and thermal protection to safeguard the device under extreme operating conditions. An internal thermal protection circuit senses die temperature and will shut down the device if the internal junction temperature exceeds approximately 145°C.

The efficiency () can simply be defined as a linear voltage regulator with an effective output voltage that is equal to two times the input voltage. Efficiency () for an ideal voltage doubler can typically be expressed as the output power divided by the input power: η= POUT PIN In addition, with an ideal voltage doubling charge pump, the output current may be expressed as half the input current. The expression to define the ideal efficiency () can be rewritten as: η= POUT VOUT × IOUT VOUT = = PIN VIN × 2IOUT 2VIN -or- η(%) = 100 ⎛ VOUT ⎞ ⎝ 2VIN ⎠ Capacitor Characteristics Ceramic composition capacitors are highly recommended over all other types of capacitors for use with the AAT3112. Ceramic capacitors offer many advantages over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low ESR, is lowest cost, has a smaller PCB footprint, and is nonpolarized. Low ESR ceramic capacitors help to maximize charge pump transient response. Since ceramic capacitors are non-polarized, they are not prone to incorrect connection damage. Equivalent Series Resistance: ESR is an important characteristic to consider when selecting a capacitor. ESR is a resistance internal to a capacitor that is caused by the leads, internal connections, size or area, material composition, and ambient temperature. Capacitor ESR is typically measured in milliohms for ceramic capacitors and can range to more than several ohms for tantalum or aluminum electrolytic capacitors. Ceramic Capacitor Materials: Ceramic capacitors less than 0.1μF are typically made from NPO or C0G materials. NPO and C0G materials typically have tight tolerance and are stable over temperature. Large capacitor values are typically composed of X7R, X5R, Z5U, or Y5V dielectric materials. Large ceramic capacitors, typically greater than 2.2μF, are often available in low-cost Y5V and Z5U dielectrics, but large capacitors are not required in AAT3112 applications. For a charge pump with an output of 4.5V and a nominal input of 2.8V, the theoretical efficiency is 80.4%. Due to internal switching losses and IC quiescent current consumption, the actual efficiency can be measured at 79.6%. These figures are in close agreement across a wide range of output load conditions. Efficiency will decrease as load current drops below 0.05mA or when the level of VIN approaches VOUT. Capacitor area is another contributor to ESR. Capacitors that are physically large will have a lower ESR when compared to an equivalent material smaller capacitor. These larger devices can improve circuit transient response when compared to an equal value capacitor in a smaller package size. Capacitor Selection High charge pump switching frequencies and large peak transient currents mandate careful printed circuit board layout. As a general rule for charge pump boost converters, all external capacitors should be located as closely as possible to the device package with minimum length trace connections. Careful selection of the four external capacitors CIN, C1, C2, and COUT is important because they will affect turn-on time, output ripple, and transient performance. Optimum performance will be obtained when low equivalent series resistance (ESR) ceramic capacitors are used. In general, low ESR may be defined as less than 100m. Layout Considerations Maximize the ground plane around the AAT3112 charge pump and make sure all external capacitors are connected to the immediate ground plane. A local component side ground plane is recommended.
