Features

The SC600 is a versatile charge pump designed for use in battery operated power supply applications. The wide input range is matched for Li-Ion battery applications. mAhxLife TM LED Drivers feature a fractional charge pump implementation with effi ciency comparable to a switching regulator without costly inductors. Only two tiny ceramic capacitors are required, and the inductorless implemen- tation provides a reduced-EMI solution. Patented low noise mode switching circuitry and constant output cur- rent allow the use of extremely small input and output capacitors. The SC600 charge pump can be used for applications that require up to 120mA of output current with a 4.0V or 4.5V output. The 5.0V output version provides up to 60mA of output current. mAhXLife TM LED drivers replace switched mode power supplies and provide comparable effi ciency with less cost, area, noise, and complexity.

7© 2006 Semtech Corp. www.semtech.com POWER MANAGEMENT SC600 Applications Information Regulated Fractional Charge Pump Operation A fractional charge pump is a voltage converter which implements switched capacitor techniques to produce an output voltage that is one of several multiples of the input voltage. Regulated fractional charge pumps (also called charge pump regulators) use a linear regulator with vari- ous charge pump confi gurations to deliver a regulated out- put over a wide input voltage range. Regulated fractional charge pumps have improved effi ciency over ordinary lin- ear regulator and charge pump circuit combinations. The improved effi ciency is achieved by implementing multiple charge pump con fi gurations on one integrated circuit. The correct charge pump con fi guration is automatically selected to meet the regulation requirements at the best possible effi ciency. The SC600 has three charge pump confi gurations (modes), which multiply the input voltage by 1x, 1.5x and 2x. The charge pump con fi gurations are implemented with two switched or 'bucket' capacitors plus the input and out- put capacitor. The bucket capacitors are confi gured for 1x mode at start-up to source current to the output capacitor and bring the output up quickly. The charge pump will begin switching in 1.5x mode. During normal operation, starting with a fully charged Li-Ion cell, the battery voltage will begin at about 4.1V. As the battery discharges and the voltage decays, the SC600 will eventually transition to 2x mode when the battery voltage is approximately 3.50V. Hysteresis is provided to prevent mode toggling. The out- put is prevented from exceeding 6.0V. This feature allows the use of 6.3V ceramic capacitors. mAhXLiFE TM Advantage The plot on page 1 shows the ef fi ciency of the SC600A. An example of a 5.0V regulated charge pump doubler is plotted to demonstrate how effective the SC600’s 1.5x mode is at improving effi ciency when the input voltage is above 3.5V. Most of the Li-Ion battery life is above 3.5V where the SC600 achieves more than 20% higher ef fi - ciency compared to the 5.0V regulated charge pump dou- bler with only a 2x mode. Following the ef fi ciency curve from left to right as the battery discharges, the SC600A 5.0V remains in 1.5x mode until 3.5V and then transitions to 2x mode. Component Versions There are four versions of the SC600. The component selection table on page 4 highlights the differences be- tween the component types. The three basic differences between the component versions are in the output volt- age, maximum output current capability, and the mode transition point. The mode transition point is the value of input voltage at which the component will transition between 1.5x and 2x SC600A (5.0V) is most ef fi cient for applications that use up to 60mA. The SC600B (4.5V) and SC600C (4.5V) have different maximum output currents and mode transition points. The lower mode transition point of the SC600C allows it to remain in 1.5x mode longer for greater power savings. The SC600B has higher output capability, up to 120mA, and S600C is rated for 60mA. The SC600D (4.0V) is for applications using up to 120mA. Start-Up Conditions Typical start-up time is less than 50μs. Caution: The SC600 must be enabled while 650kHz or 262kHz is selected to pre- vent over-voltage during start-up. LED Bias and Backlighting Applications When using the SC600 for LED bias, note that the SC600C and SC600D require the same input power per unit of output current even though the SC600C is more effi cient. Also, the SC600A will have the same input power as the SC600B though the SC600A is more effi cient. The following plots of Input Power vs. Input Voltage high- light the differences in application of the four component versions. To achieve the lowest possible input power, it is desirable for the charge pump to remain in 1.5x mode until the input voltage is as low as possible. The transi- tion points from 1.5x to 2x are identifi ed in the plot where the input power steps upward as the input voltage moves lower.

Brightness Control with PWM Input Brightness control using a PWM input can be achieved with the application circuit below. Note that by connecting CX8 to the PWM signal the switching frequency is changed as the PWM signal changes. The charge pump operates at 262kHz during the on-time when there is a demand for current, and then changes to 32kHz when there is no load current. This is done to save battery power by taking ad- vantage of the lower 280 μA quiescent current at 32kHz. The ripple voltage seen at the output is reasonable for LED applications, but the output capacitance can be in- creased to reduce the ripple if required. The sum of the LED currents for this circuit is 55mA during the on-time.

10© 2006 Semtech Corp. www.semtech.com POWER MANAGEMENT SC600 Applications Information (Cont.) Comparison with Other Regulation Methods In many instances, a charge pump regulator is the best choice for portable power applications. These regulators offer many advantages over switch mode regulators. A smaller bill of materials, less layout area, lower compo- nent height, less noise, no EMF, and less overall circuit cost are typical reasons to use this type of regulation. In some cases the effi ciency of a charge pump regulator ex- ceeds the effi ciency of a switch mode regulator. Inductors are often the largest and most expensive dis- crete component in a design. Because there are no in- ductors used in the SC600, cost, noise, layout area, as well as the the EMF associated with the inductor, are eliminated. The SC600’s fi xed frequency harmonics are an advantage in portable communications equipment, such as cellular telephones. The SC600 has distinct frequencies of op- eration, so the harmonics are predictable. The harmonics are not fi xed in a switch mode regulator. Ripple Performance Examples of the output ripple, charge pump frequency and capacitor size are listed in Table 2. Switch mode regulators have harmonics which vary due to the pulse width modulation used to regulate the output. Varying harmonics can make it diffi cult to ensure accept- able noise performance over the entire operating range. Many switch mode regulators have increased voltage rip- ple on the output during pulse skipping mode due to large periods of time when no current is supplied to the output. The SC600 supplies current to the output continuously, so the voltage ripple is less than a switch mode regula- tor, even with greatly reduced output capacitance. The SC600 delivers a continuous current to the output during 1x, 1.5x and 2x modes. Most of the battery life requires 1.5x mode. Frequency Selection CX8 and CD4 are frequency select inputs; input from a µP or other device may be used to change the charge pump frequency at any time (as shown in Table 1). The opti- mal frequency will depend upon the capacitor values, the load current, and the acceptable amount of output ripple. Lower frequencies will be more effi cient, while higher fre- quencies will support higher output currents with lower ripple. ycneuqerFgnihctiwS8 XC4 DC zHk230 0 zHk80 1 zHk2621 0 zHk0561 1 Table 1 -Frequency Selection Logic .oNtraP] zHk[.qerFI TUO ]Am[] p-pVm[elppiRtuptuO edomx5.1 ]p-pVm[elppiRtupuO edomx2 C TUO ]Fμ[C TEKCUB ]Fμ[ V0.5A006CS 85 5 65 11 1 230 20 515 21 1 2620 65 20 21 1 0560 60 15 11 1 0560 60 25 23 3.01 Table 2 -Ripple P erformance

Mode Transition Impedance The mode transition impedance Ro refers to the output resistance of the charge pump before a transition to a stronger mode occurs. Ro is dependent upon the frac- tional charge pump, switching frequency, bucket capaci- tor value, bucket capacitor ESR, and the internal switch resistances. Ro is proportional to, fC˜ Ro can be measured to verify a low transition imped- ance. Before measuring Ro, select the capacitors, set the operating frequency and a constant load current. Find the input voltage just before a weak to strong mode tran- sition (i.e., 1.5x to 2x mode). Measure V IN, VOUT, a n d IOUT before the transition.

A lower value of Ro will improve efficiency, so low ESR ceramic capacitors are required. An X7R or X5R dielec- tric is recommended. Y5V dielectric can require 2 to 3 times the rated value of an X7R dielectric for the same performance over the operating temperature range. Efficiency Efficiency for the SC600 is defined as, η = V O I O˜ V IN mode I O˜ I Q

Alternately, the mode can be identi fi ed by identifying the voltage at the bucket capacitor, CF1 with an oscilloscope. Calculating Power Dissipation The power dissipated by the SC600 is calculated as, P D = PIN - POUT PD = VIN · (mode IO + IQ) - VO · IO Suggested Capacitors The following is a short list of some of the manufacturers and types of multi-layer ceramic capacitors that are sug- gested for the SC600. Short-Circuit and Over-Temperature Protection The output current is limited to 600mA to protect against short-circuit conditions. Over-temperature protection is also provided. Design and Layout Considerations The layout example on page 15 uses the 1206 case size for the capacitors, so a smaller layout area is possible. The bucket capacitors and the SC600 are on the same side of the card. To minimize trace inductance, traces are short and wide with no vias to the bucket capacitors. The input and output caps are on the bottom side directly un- der the SC600 and vias are used to connect directly to copper shapes used for the input and output. The input and output capacitors and Pin 8 should be connected to ground very near the SC600. rerutcafunaMr ebmuNtraP] Fμ[ecnaticapaCe pyTcirtceleiDe ziSegakcaPAIEe gatloV gnitaR XVAK 522CZ50802 .2R 7X5 080V 01 XVAK 501CZ50800 .1R 7X5 080V 01 XVAK 433CZ50803 3.0R 7X5 080V 01 cinosanaPK 522J0BY2JCE2 .2R 5X5 080V 3.6 cinosanaP5 01A1BY2JCE0 .1R 7X5 080V 01 cinosanaPK 501J0BV1JCE0 .1R 5X2 040V 3.6 cinosanaPK 433J0BV1JCE3 3.0R 5X3 060V 3.6 KDT5 01A1R5X8061C0 .1R 5X3 060V 01 KDTZ 601A1V5Y2021C0 .1R 5X5 080V 01 KDTk 433A1R5X8061C3 3.0R 5X3 060V 01
