DISCONTINUOUS CONDUCTION MODE Detailed Description The EL7513 is a constant current boost regulator specially designed for driving white LEDs. It can drive up to 4 LEDs in series or 12 LEDs in parallel/series configuration and achieves efficiency up to 91%. The brightness of the LEDs is adjusted through a voltage level on the CNTL pin. When the level falls below 0.1V, the chip goes into shut-down mode and consumes less than 1µA of current for VIN less than 5.5V. Steady-State Operation EL7513 is operated in constant frequency PWM. The switching is around 1MHz. Depending on the input voltage, the inductance, the type of LEDs driven, and the LED’s current, the converter operates at either continuous conduction mode or discontinuous conduction mode (see waveforms). Both are normal. Brightness Control LED’s current is controlled by the voltage level on CNTL pin (VCNTL). This voltage can be either a DC or a PWM signal with frequency less than 200Hz (for C3 = 4700pF). When a higher frequency PWM is used, an RC filter is recommended before the CNTL pin (see Figure 20). FIGURE 19. OVER VOLTAGE PROTECTION (LED DISCONNECTED) The relationship between the LED current and CNTL voltage level is as follows: V CNTL I LED = ---------------------------13.33 × R 1 (EQ. 1) When R1 is 5Ω, 1V of VCNTL conveniently sets ILED to 15mA. The range of VCNTL is 250mV to 5.5V. Shut-Down When VCNTL is less than 100mV, the converter is in shutdown mode. The max current consumed by the chip is less than 1µA for VIN less than 5.5V. Over-Voltage Protection When an LED string is disconnected from the output, VO will continue to rise because of no current feedback. When VO reaches 18V (nominal), the chip will shut down. The output voltage will drop. When VO drops below 16V (nominal), the chip will boost output voltage again until it reaches 18V. This hiccough continues until LED is applied or converter is shut down. When designing the converter, caution should be taken to ensure the highest operating LED voltage does not exceed 17V, the minimum shut-down voltage. There is no external component required for this function. Component Selection PWM SIGNAL 100k CNTL 0.1µF COMP The input and output capacitors are not very important for the converter to operate normally. The input capacitance is normally 0.22µF - 4.7µF and output capacitance 0.22µF - 1µF. Higher capacitance is allowed to reduce the voltage/current ripple, but at added cost. Use X5R or X7R type (for its good temperature characteristics) of ceramic capacitors with correct voltage rating and maximum height. FIGURE 20. PWM BRIGHTNESS CONTROL 9 FN7112.5 December 22, 2008 EL7513 When choosing an inductor, make sure the inductor can handle the average and peak currents giving by following formulas (80% efficiency assumed): The diode should be Schottky type with minimum reverse voltage of 20V. The diode's peak current is the same as inductor's peak current, the average current is IO, and RMS current is: IO × VO I LAVG = -----------------------0.8 × V IN (EQ. 2) I DRMS = 1 I LPK = I LAVG + --- × ΔI L 2 (EQ. 3) Ensure the diode's ratings exceed these current requirements. V IN × ( V O – V IN ) ΔI L = --------------------------------------------L × VO × FS (EQ. 4) (EQ. 5) White LED Connections where: • ΔIL is the peak-to-peak inductor current ripple in Ampere • L inductance in µH • FS switching frequency, typical 1MHz A wide range of inductance (6.8µH - 68µH) can be used for the converter to function correctly. For the same series of inductors, the lower inductance has lower DC resistance (DCR), which has less conducting loss. But the ripple current is bigger, which generates more RMS current loss. Figure 11 shows the efficiency of the demo board under different inductance for a specific series of inductor. For optimal efficiency in an application, it is a good exercise to check several adjacent inductance values of your preferred series of inductors. For the same inductance, higher overall efficiency can be obtained by using lower DCR inductor. EFFICIENCY vs IO 85 L = 22µH 83 L = 33µH One leg of LEDs connected in series will ensure the uniformity of the brightness. 18V maximum voltage enables 4 LEDs can be placed in series. However, placing LEDs into series/parallel connection can give higher efficiency as shown in the efficiency curves. One of the ways to ensure the brightness uniformity is to prescreen the LEDs. PCB Layout Considerations The layout is very important for the converter to function properly. Power Ground ( ) and Signal Ground ( ) should be separated to ensure the high pulse current in the power ground does not interference with the sensitive signals connected to Signal Ground. Both grounds should only be connected at one point right at the chip. The heavy current paths (VIN-L-LX pin-PGND, and VIN-L-D-C2-PGND) should be as short as possible. The trace connected to the CS pin is most important. The current sense resister R1 should be very close to the pin When the trace is long, use a small filter capacitor close to the CS pin. The heat of the IC is mainly dissipated through the PGND pin. Maximizing the copper area around the plane is preferable. In addition, a solid ground plane is always helpful for the EMI performance. VIN = 3.3V FOR DIFFERENT L EFFICIENCY (%) I LAVG × I O L = 15µH The demo board is a good example of layout based on the principle.
