DATA SHEET AAT3152 High Efficiency 1X/1.5X/2X Charge Pump for White LED Applications General Description Features The AAT3152 is a low noise, constant frequency charge pump DC/DC converter that uses a tri-mode load switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency for white LED applications. The AAT3152 is capable of driving four-channel LEDs from a 2.7V to 5.5V input. The current sinks may be operated individually or in parallel for driving higher-current LEDs. A low external parts count (two 1µF flying capacitors and two small 1µF capacitors at VIN and VOUT) makes this part ideally suited for small, battery-powered applications. •VIN Range: 2.7V to 5.5V • Fully Programmable Current with Single Wire ▪ Eight-Step Current: 20mA to 50µA ▪ Individual Main-Sub Group Control ▪ Low IQ (50µA) at Light Load • Tri-Mode 1X, 1.5X, and 2X Charge Pump for Maximum Efficiency and VF Coverage • Drives 1-4 Channels of LEDs • No Inductors, Low Noise Operation • 1MHz Constant Switching Frequency • Small Application Circuit • Built-In Thermal Protection • Built-In Auto-Disable for Short-Circuit • Automatic Soft Start •IQ <1µA in Shutdown • Thermally-Enhanced 3x3mm 12-Pin TDFN Package Skyworks’ S2Cwire™ (Simple Serial Control) serial digital input is used to enable, disable, and set current for each LED with eight settings (20mA down to 50µA) including main/sub-display group control.

To maximize power conversion efficiency, an internal sensing circuit monitors the voltage required on each constant current sink input and sets the load switch and charge pump modes based on the input battery voltage and the current sink input voltage. As the battery discharges over time, the AAT3152 charge pump is enabled when any of the four current sink inputs near dropout. The charge pump initially starts in 1.5X mode. If the charge pump output drops enough for any current source output to become close to dropout, the charge pump will automatically transition to 2X mode. The AAT3152 requires only four external components: two 1µF ceramic capacitors for the charge pump flying capacitors (C1 and C2), one 1µF ceramic input capacitor (CIN), and one 0.33µF to 1µF ceramic charge pump output capacitor (COUT). The constant current sink levels for D1 to D4 are set via the serial interface. No PWM (pulse width modulation) or additional control circuitry is needed to control LED brightness. This feature greatly reduces the burden on a microcontroller or system IC to manage LED or display brightness, allowing the user to “set it and forget it.” With its high-speed serial interface (up to 1MHz data rate), the input sink current of the AAT3152 can be changed successively to brighten or dim LEDs, giving the users real-time control of LED brightness. Because the inputs D1 to D4 are true independent constant current sinks, the voltage observed on any single given input will be determined by the actual forward voltage (VF) for the LED being driven. The four constant current sink inputs (D1 to D4) can drive four individual LEDs with a maximum current of 20mA each. The unused sink inputs must be connected to VOUT, otherwise the part will operate only in 2X charge pump mode. The S2Cwire serial interface enables the AAT3152 and sets the current sink magnitudes. S2Cwire addressing allows independent control of two groups of current sink input: D1-D3 and D4. 8 S2Cwire Serial Interface The current sink input magnitude on the AAT3152 is controlled by Skyworks' S2Cwire serial digital input. It relies on the number of rising edges of the EN/SET pin to address and load the registers. S2Cwire latches data or address after the EN/SET pin has been held high for time TLAT. The interface records rising edges of the EN/ SET pin and decodes them into 16 different states, as indicated in the Current Setting table. There are four brightness levels for main or sub-display group with the possibility of individually turning ON or OFF each group.

During this low-current mode, the internal supply current reduces to only 80µA typical. The EN/SET timing is designed to accommodate a wide range of data rates. After the first rising edge of EN/SET, the charge pump is enabled and reaches full capacity after the soft-start time (TSS). During the soft-start time, multiple clock pulses may be entered on the EN/SET pin to set the final output current level with a single burst of clocks. Alternatively, the EN/SET clock pulses may be entered one at a time to gradually increase the LED brightness over any desired time period. The current outputs remain constant as long as EN/SET remains in a logic high state. The current outputs are switched off after EN/SET has remained in a low state for at least the TOFF timeout period; then, the AAT3152 enters shutdown mode and draws less than 1µA from VIN. Data are reset to 0 during shutdown. The counter can be clocked at speeds up to 1MHz, such that intermediate states are not visible. The first rising edge of EN/SET enables the IC and initially sets the output LED current to 20mA. Once the final clock cycle is input for the desired brightness level, the EN/SET pin is held high to maintain the device output current at the programmed level. The device is disabled 500µs (TOFF) after the EN/SET pin transitions to a logic low state.

After the IC is enabled and started up, a test current of 150µA (typical) is forced through each sink channel. The channel will be disabled if the voltage of that particular current sink pin does not drop to a certain threshold. This feature is very convenient for disabling an unused channel (by tying the DX pin to VOUT) or during an LED fail short event. Thermal Protection The AAT3152 has a built-in thermal protection circuit that will shut down the charge pump if the die temperature rises above the thermal limit, as is the case during a short circuit of the VOUT pin.

LED applications may include main and sub-LCD display backlighting, camera photo-flash applications, color (RGB) LEDs, infrared (IR) diodes for remotes, and other loads benefiting from a controlled output current generated from a varying input voltage. Since the D1 to D4 input current sinks are matched with negligible voltage dependence, the LED brightness will be matched regardless of the specific LED forward voltage (VF) levels. In some instances (e.g., in high-luminousoutput applications such as photo-flash), it may be necessary to drive high-VF type LEDs. The low-dropout current sinks in the AAT3152 make it capable of driving LEDs with forward voltages as high as 4.7V at full current from an input supply as low as 3.0V. Outputs can be paralleled to drive high-current LEDs without complication. Capacitor Characteristics Ceramic composition capacitors are highly recommended over all other types of capacitors for use with the AAT3152. 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. Device Switching Noise Performance Ceramic Capacitor Materials The AAT3152 operates at a fixed frequency of approximately 1MHz to control noise and limit harmonics that can interfere with the RF operation of cellular telephone handsets or other communication devices. Back-injected noise appearing on the input pin of the charge pump is 20mV peak-to-peak, typically ten times less than inductor-based DC/DC boost converter white LED backlight solutions. The AAT3152 soft-start feature prevents noise transient effects associated with in-rush currents during start-up of the charge pump circuit. 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. Larger 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 capacitors greater than 1µF are typically not required for AAT3152 applications. 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 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 100mW. A value of 1µF for all four capacitors is a good starting point when choosing capacitors. If the LED current sources are only programmed for light current levels, then the capacitor size may be decreased. 10 Thermal Protection The AAT3152 has a built-in thermal protection circuit that will shut down the charge pump if the die temperature rises above the thermal limit, as is the case during a short circuit of the VOUT pin.
