The CM9156B charge pump is the perfect driver for such portable applications, providing efficiency, compact overall size, low system cost and minimum EMI. The CM9156B contains a linear low dropout (LDO) regulator followed by a 1.5x fractional charge pump that converts the nominal lithium-ion (Li-Ion) or lithium polymer battery voltage levels (3.6V) by a gain of 1.5 times and regulates the converted voltage to 4.5V, ±5%, enough to drive the forward voltage drop of white LEDs. The CM9156B requires only two external switched, or bucket, capacitors, plus an input and an output capacitor, providing for a compact, low profile design. In many applications, all these can conveniently be the same value of 1.0μF, commonly available in a compact 0805 surface mount package. put capacitors are charged during the power-up of the device. The input voltage, VIN, passes through an LDO preregulator that compares the output voltage to a precision bandgap reference. After the LDO, the charge pump boosts the LDO voltage by 1.5 times. A feedback circuit to the LDO monitors the output voltage, and when the output voltage reaches 4.5V, the LDO output will operate at about 3V, regulating the device output at 1.5 x 3V = 4.5V. The charge pump uses two phases from the oscillator to drive internal switches that are connected to the bucket capacitors, C1 and C2, as shown in Figure 1. In the first switch position, the bucket capacitors are connected in series and each are charged from the LDO to a voltage of VLDO/2. The next phase changes the switch positions so that C1 and C2 are put in parallel, and places them on top of VLDO. The resulting voltage across COUT is then; VLDO+1/2VLDO = 1.5 x VLDO. The CM9156B is intended for white LED applications, but it can drive most all types of LEDs with a forward voltage drop of less than 4V. VOUT ILED = C OUT VIN The LED current is determined by its series resistor, RLED, and is approximately; C1 ½ VLDO FB LDO VLDO 4.5 V − VFWD _ LED RLED C2 ½ VLDO Typical white LEDs have a forward voltage drop, VFWD_LED, of 3.5V to 3.7V. Like single-junction devices, white LEDs often have poorly matched forward voltages. If the LEDs were put in parallel without a series resistor, the current in the paralleled branches would vary, resulting in non-uniform brightness. RLED, in addition to setting the current, compensates for this variation by functioning as a ballast resistor, providing negative feedback for each paralleled LED. Charge C1 and C2 to ½ V LDO VOUT VIN C1 C OUT ½ VLDO FB LDO VLDO CM9156B Operation C2 ½ VLDO When a voltage exceeding the undervoltage lockout threshold (UVLO) is applied to the VIN pin, the CM9156B initiates a softstart cycle, typically lasting 1000μs. Softstart limits the inrush current while the out- Figure 1. Switch operation © 2006 California Micro Devices Corp. All rights reserved. 8 490 N.

The smart CM9156B knows this, and if the input voltage rises above 5V, the charge pump automatically disables, removing the voltage gain stage and the output is then provided directly through the LDO, regulated at 4.5V. This increases the efficiency and minimizes chip heating in this operating condition. The CM9156B has over-temperature and over-current protection circuitry to limit device over-stress and failure during short circuit conditions. An overcurrent condition will limit the output current (approximately 400mA ~ 600mA) and will cause the output voltage to drop, until automatically resetting after removal of the excessive current. Over-temperature protection disables the IC when the junction is about 135-ºC, and automatically turns-on the IC when the junction temperature drops by approximately 15-ºC. For an ideal 1.5x charge pump, IIN = 1.5 x IOUT, and the efficiency may be expressed as; POUT ⎛ VOUT × IOUT ⎞ VOUT ⎟= ≈ ⎜⎜ ⎟ 1.5 × V PIN V 1 . 5 I × × OUT ⎠ IN ⎝ IN VOUT = 4.5V, ∴ η≈ 4.5V 1.5 × VIN The ideal 2x charge pump can be similarly expressed; P OUT 4.5V ------------- ≈ ---------------------P IN 2.0 × V IN In 1x mode, when the input voltage is above the output voltage, the part functions as a linear regulator and the ideal efficiency is simply Vout/Vin. The typical conversion efficiency plots for these modes, with some losses, are shown in Figure 2. A conventional charge pump with a fixed gain of 2x will usually develop more voltage than is needed to drive paralleled white LEDs from Li-Ion sources. This excessive gain develops a higher internal voltage, reducing system efficiency and increasing battery drain in portable devices. A fractional charge pump with a gain of 1.5x is better suited for driving white LEDs in these applications. The CM9156B charge pump automatically switches between 2 conversion gains, 1x and 1.5x, allowing high efficiency levels over a wide operating input voltage range. The 1x mode allows the regulated LDO voltage to pass directly through to the output when sufficient input voltage is available; the 1.5x charge pump is enabled only when the battery input is too low to sustain the output load. At nominal loads, the switching losses and quiescent current are negligible. If these losses are ignored for simplicity, the efficiency, , for an ideal 1.5x charge pump can be expressed as the output power divided by the input power; P OUT η ≈ ------------P IN Efficiency Vout=4.5V 100 Efficiency (%) Efficiency 1X 85 70 CM9156B dual mode 55 1.5X 2X 40 3.0 3.5 4.0 4.5 5.0 5.5 6.0 Input Voltage (V) Figure 2. Ideal efficiency curves As can be seen, the CM9156B, with 1x and 1.5x modes, has better efficiency in this application than a fixed 2x charge pump. At low battery voltages, the higher efficiency of the CM9156B charge pump’s 1,5x gain reduces the battery drain. At higher input voltages, above 4.9V typically seen when the system is running off an AC adapter, the CM9156B, operating the © 2006 California Micro Devices Corp. All rights reserved. 04/26/06 490 N.

LED Brightness Control CM9156B Design Example Capacitor Selection The external bucket capacitors will affect the output impedance of the converter, so surface-mount, low ESR ceramic capacitors are recommended. Tantalum and Aluminum capacitors should not be used because their ESR is too high. The ceramic dielectric must be stable over the operating temperature and voltage range, X7R or X5R dielectrics are recommended. In noise sensitive applications, output ripple can be further reduced by increasing the capacitance of the output capacitor. Reflected input ripple current depends on the impedance of the VIN source, which includes the PCB traces. Increasing the input capacitor will reduce this ripple. The input capacitor also affects the output voltage ripple. All the capacitors should be located close to the device for best performance. Frequency Selection The optimal switching frequency depends on the allowable system current draw, the load current, ripple and EMI requirements. The CM9156B’s operating frequency choices are 262kHz or 650kHz. These two frequencies are selected by programming the CLK input. Refer to Table 1. The supply current for a charge pump is proportional to its switching frequency. A lower switching frequency allows reduced quiescent current for more efficient operation, but reduces the output current capability and in some cases, causes higher ripple. Higher frequencies are used when larger load currents are demanded. The frequency is typically selected to achieve maximum efficiency while avoiding sensitive frequencies with the switching fundamental and its harmonics. The switching frequency can be set outside the critical frequency spectrums of cellular communications bandwidths. Once set, the switching frequency and its harmonics remain fixed, making filtering easy. V in VOUT C 2P C 1P C 1N VIN GND C 2N C LK ENA CM9156B PWM input Figure 3. PWM brightness control, lowered quiescent current Changes in ambient light often require the backlight display intensity to be adjusted, usually to conserve battery life. There are simple solutions to lowering the LED brightness when using the CM9156B. A PWM signal applied to the ENA pin can be used to control the brightness, which is more efficient than other solutions that dissipate unwanted LED current in the series resistors. It also maintains the white LED color fidelity by avoiding color temperature variations that come with bias current changes. The LED intensity is determined by the PWM duty cycle, which can vary from 0% to 100%. In the configuration shown in Figure 3, the brightness is controlled by the PWM signal applied to the LEDs. Decreased Duty Cycle will lower the LED brightness, See Figure 4 and Figure 5. The same signal is also applied to the CM9156B, reducing the charge pump switching frequency via the CLK control. When the PWM signal is high, CLK goes high, the operating frequency is 650kHz (refer to Table 1), and the LED current path is complete through the switch. When the PWM signal is low, the LED current is stopped as the switch turns off, and the switching frequency of the charge pump becomes 262kHz (CLK = 0). Operating the charge pump at the lower frequency lowers the quiescent current when the charge pump is operational (the input voltage below 5V). © 2006 California Micro Devices Corp.

These cameras typically utilize a WLED flash to illuminate the picture subject in low light conditions. The CM9156B is easily adapted to such an application. Figure 6 is a typical application using the CM9156B as a WLED flash driver, which is ideal for this application because it is capable of driving up to 180mA from a Liion battery. The One-shot is used to create a single pulse of a set duration to the ENA pin of the CM9156B.

The series resistor is chosen based on the forward drop of the module LEDs (typically 3.3V to 3.8V) and the number of parallel LEDs being driven. 20 uSec/div Figure 4. High brightness waveforms The recommended PWM frequency is between 100 Hz and 20kHz. If a frequency of less then 100 Hz is used, flicker might be seen in the LEDs. The frequency should also be greater than the refresh rate of the TFT display. Higher frequencies will cause a loss of brightness control linearity. In addition, higher frequency can cause chromaticity shifts because the fixed rise and fall times of the PWM signal will shift the forward current.

Low brightness waveforms The charge pump is rapidly charging and discharging its external capacitors, so external traces to the capacitors should be made as wide and short as allowable to minimize inductance and high frequency ringing. The four capacitors should be located as close as practical to the charge-pump, particularly C1 and C2, which have the highest dv/dt. Connect ground and power traces to the capacitors through short, low impedance paths. Use a solid ground plane, ideally on the backside of the PCB, which should carry only ground potential. Connect the ground-side of Cin, Cout and the chip GND as close as practical. For best thermal performance, the exposed backside lead frame should be soldered to the PCB. © 2006 California Micro Devices Corp. All rights reserved. 04/26/06 490 N.
