DATA SHEET AAT3190 Positive/Negative Charge Pump for Voltage Bias General Description Features The AAT3190 charge pump controller provides the regulated positive and negative voltage biases required by active matrix thin-film transistor (TFT) liquid-crystal displays (LCDs), charge-coupled device (CCD) sensors, and organic light emitting diodes (OLEDs). Two low-power charge pumps convert input supply voltages ranging from 2.7V to 5.5V into two independent output voltages. • • • • • • • • • • • • • The dual low-power charge pumps independently regulate a positive (VPOS) and negative (VNEG) output voltage. These outputs use external diode and capacitor multiplier stages (as many stages as required) to regulate output voltages up to ±25V. Built-in soft-start circuitry prevents excessive in-rush current during start-up. A high switching frequency enables the use of small external capacitors. The device’s shutdown feature disconnects the load from VIN and reduces quiescent current to less than 1.0μA.

REF - FBN + Functional Description Dual Charge Pump Regulators The AAT3190 provides low-power regulated output voltages from two individual charge pumps. Using a single stage, the first charge pump inverts the supply voltage (VIN) and provides a regulated negative output voltage. The second charge pump doubles VIN and provides a regulated positive output voltage. These outputs use external Schottky diodes and capacitor multiplier stages (as many as required) to regulate up to ±25V. A constant switching frequency of 1MHz minimizes the output ripple and capacitor size. Negative Charge Pump During the first half-cycle, the P-channel MOSFET turns on and the flying capacitor C7 charges to VIN minus a diode drop (Figure 1). During the second half-cycle, the P-channel MOSFET turns off and the N-channel MOSFET turns on, level shifting C7. This connects C7 in parallel with the output reservoir capacitor C10. If the voltage across C10 minus a diode drop is less than the voltage across C7, current flows from C7 to C10 until the diode turns off. 8 Positive Charge Pump During the first half-cycle, the N-channel MOSFET turns on and charges the flying capacitor C4 (Figure 2). During the second half-cycle, the N-channel MOSFET turns off and the P-channel MOSFET turns on, level shifting C4 by the input voltage. This connects C4 in parallel with the reservoir capacitor C5. If the voltage across C5 plus a diode drop is less than the level shifted flying capacitor (C4 + VIN), charge is transferred from C4 to C5 until the diode turns off. Voltage Reference The voltage reference is a simple band gap with an output voltage equal to VBE + K*VT. The band gap reference amplifier has an additional compensation capacitor from the negative input to the output. This capacitor serves to slow down the circuit during startup and soft starts the voltage reference and the regulator output from overshoot. The reference circuit amplifier also increases the overall PSRR of the device. An 80k resistor serves to isolate and buffer the amplifier from a small internal filter capacitor and an optional large external filter capacitor.

Enable and Start-up The AAT3190 is disabled by pulling the EN pin low. The threshold levels lie between 0.5V and 1.5V. Even though the quiescent current of the IC during shutdown is less than 1μA, the positive output voltage (VOP) and any load current associated with it does not disappear without the complete removal of the input voltage. This is due to the fact that with no switching of the DRVP pin, the input voltage simply forward biases the Schottky diodes associated with the VOP charge pump, providing a path for load current to be drawn from the input voltage. Depending on the application, the supplies must be sequenced properly to avoid damage or latch-up. The AAT3190 start-up sequence ramps up the VOP output 200μs after the VON output is present. The AAT3190-1 ramps up the positive supply before the negative supply. Over-Temperature Protection A logic control circuit will shut down both charge pumps in the case of an over-temperature condition. Under-Voltage Lockout A UVLO circuit disables the AAT3190 when the input voltage supply is lower than 1.8V nominal.

The number of stages required can be estimated by: VOP - VIN np = V - 2V IN F for the positive output and VON nn = 2V - V F IN VOP The positive output voltage is set by way of a resistive divider from the output (VOP) to the FBP and ground pin. Limiting the size of R4 reduces the effect of the FBP bias current. For less than 0.1% error, limit R4 to less than 12k. VREF 1.2V IPGM = R4 = 12kΩ = 100μA IFBP 0.1μA IPGM = 100μA = 0.1% Once R4 has been determined, solve for R3: R3 = R4 · for the negative output. When solving for np and nn, round up the solution to the next highest integer to determine the number of stages required. VON The negative output voltage is adjusted by a resistive divider from the output (VON) to the FBN and REF pin. The maximum reference voltage current is 50μA; therefore, the minimum allowable value for R2 of Figure 1 is 24k. It is best to select the smallest value possible for R2, as this will keep R1 to a minimum. This limits errors due to the FBN input bias current. The FBN input has a maximum input bias current of 100nA. Using the full 50μA reference current for programming VON: VREF 1.2 IPGM = R2 = 24.1k = 50μA ⎛ VO ⎞ -1 V ⎝ REF ⎠ Flying and Output Capacitor The flying capacitor minimum value is limited by the output power requirement, while the maximum value is set by the bandwidth of the power supply. If CFLY is too small, the output may not be able to deliver the power demanded, while too large of a capacitor may limit the bandwidth and time required to recover from load and line transients. A 0.1μF X7R or X5R ceramic capacitor is typically used. The voltage rating of the flying and reservoir output capacitors varies with the number of charge pump stages. The reservoir output capacitor should be roughly 10 times the flying capacitor. Use larger capacitors for reduced output ripple. Positive Output Capacitor Voltage Ratings will limit the error due to the input bias current at FBN to less than 0.2%: The absolute steady-state maximum output voltage (neglecting the internal RDS(ON) drop of the internal MOSFETs) for the nth stage is: IFBN 0.1μA IPGM = 50μA = 0.2% VBULK(n) = (n + 1) · VIN - 2 · n · VFWD With R2 selected, R1 can be determined: R1 = VNEG · R2 -VREF where VFWD is the estimated forward drop of the Schottky diode. This is also the voltage rating required for the nth bulk capacitor in the positive output charge pump. The voltage rating for the nth flying capacitor in the positive stage is: VFLY(n) = VBULK(n + 1) - VFWD where VBULK(0) is the input voltage (see Table 1). 10 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 202082A • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice. • June 21, 2012 DATA SHEET AAT3190 Positive/Negative Charge Pump for Voltage Bias VIN = 5.0V, VFWD = 0.3V Stages (n) VBULK(n) VFLY(n) 1 2 3 4 5 6 9.4V 13.8V 18.2V 22.6V 27.0V 31.4V 4.7V 9.1V 13.5V 17.9V 22.3V 26.7V Table 1: Positive Output Capacitor Voltages.

Single Output Operation Input Capacitors Input Capacitor The primary function of the input capacitor is to provide a low impedance loop for the edges of pulsed current drawn by the IC. A low ESL X7R or X5R type ceramic capacitor is ideal for this function. The size required will vary depending on the load, output voltage, and input voltage characteristics. Typically, the input capacitor should be 5 to 10 times the flying capacitor. If the source impedance of the input supply is high, a larger capacitor may be required. To minimize stray inductance, the capacitor should be placed as closely as possible to the IC. This keeps the high frequency content of the input current localized, minimizing radiated and conducted EMI. Rectifier Diodes For the rectifiers, use Schottky diodes with a voltage rating of 1.5 times the input voltage. The maximum steadystate voltage seen by the rectifier diodes for both the positive and negative charge pumps (regardless of the number of stages) is: VREVERSE = VIN - VF The BAT54S dual Schottky is offered in a SOT23 package that provides a convenient pin-out for the voltage doubler configuration. The BAT54SDW quad Schottky in a SOT363 (2x2mm) package is a good choice for multiplestage charge pump configuration (see Figure 3, Evaluation Board Schematic). PC Board Layout The input and reference capacitor should be placed as close to the IC as possible. Place the programming resistors (R1-R4) close to the IC, minimizing trace length to FBN and FBP. Figures 4 and 5 display the evaluation board layout with the TSOPJW-12 package. If only one of the two channels is needed, it is possible to disable either output. Connect the respective FB pin to VIN to disable the output (e.g., connect FBN to VIN in order to disable the negative output).
