Data Sheet Rev. 1.00 / April 2013 ZSLS7031 Isolated and Non-isolated Flyback LED Driver with Active PFC LED Lighting ICs Wise and Efficient ZSLS7031 Isolated and Non-isolated Flyback LED Driver with Active PFC Brief Description Features The ZSLS7031 is a primary-side controlled, peakcurrent-mode high-brightness LED flyback driver that supports both isolated and non-isolated designs with active power factor correction (PFC). The device works at a constant frequency in discontinuous conduction mode to provide constant power to the output. It eliminates the need for an opto-coupler, TL431 shunt regulator, or any other type of secondary-side feedback device. It operates from a wide input voltage range of 85VAC to 265VAC. The ZSLS7031 integrates over-current and overvoltage protection, as well as a thermal shutdown to halt the switching action in the event of abnormally high operating temperatures.

Figure 2.1 2.2 ZSLS7031 Block Diagram Startup Voltage After power is applied to the circuit, R3 provides a trickle current to allow C4 to begin charging. The ZSLS7031 starts functioning when the voltage across C4 reaches the startup threshold VTH_S, which is approximately 16.5V (see specification 1.3.1). The value of R3 and C4 can be determined by the input voltage. Choosing a larger value of R3 increases the startup time but reduces the losses after the circuit is running. A low ESR capacitor of 2.2µF rated for 25V is recommended for C4. 2.3 Soft Start Control When the ZSLS7031 is initially powered up, the internal automatic gain control (AGC) output is at the minimum value, so the peak CS threshold is initially much less than 0.5V. The AGC steps up cycle-by-cycle until the CS threshold at the peak of the input sine wave is equal to 0.5V. With this technique, it will take several cycles of the AC waveform for the final value of current to be attained, as shown in Figure 2.2.

When the voltage at VCC is smaller than the VGATEclp threshold (see specification 1.3.3), the output high voltage of the GATE output is approximately VCC. When the voltage of VCC is greater than the VGATEclp threshold, the output high voltage of GATE is limited to the VGATEclp threshold. 2.5 VSINE Detection Network and Active PFC The voltage VSINE at the VSINE pin is used to control the waveform of the input current to ensure that it follows the input voltage waveform, VBULK, to achieve a high power factor (PF) and low total harmonic distortion (THD) performance, as demonstrated in Figure 2.3. Data Sheet May 7, 2013 © 2013 Zentrum Mikroelektronik Dresden AG — Rev.1.00 All rights reserved. The material contained herein may not be reproduced, adapted, merged, translated, stored, or used without the prior written consent of the copyright owner. The information furnished in this publication is subject to changes without notice. 11 of 21 ZSLS7031 Isolated and Non-isolated Flyback LED Driver with Active PFC Figure 2.3 Active PFC VSINE is used to detect the input voltage that controls the peak current waveform in the primary inductor. An integrated AGC ensures that the peak current of the inductor remains constant with changing input voltage. This allows the ZSLS7031 to actively correct the power factor while maintaining a constant power output during operation. The resistor network connected to VSINE should be computed so that the peak input voltage condition corresponds to ~2.4VDC. For example, for 265VAC, the peak voltage is 374.7V. At 374.7V input, the output of the network should be 2.4V; therefore values of R1=1.86M and R2 = 12k are appropriate. Precision resistors of 1% tolerance or better must be used. A small capacitor, C2, is used to filter high frequency noise that may couple to the VSINE pin. 2.6 Operating Frequency The operating frequency is set by connecting a resistor between the FSET pin and ground. The relationship between the frequency and resistance is given in equation (1). f kHz Data Sheet May 7, 2013 15 103 RSET k © 2013 Zentrum Mikroelektronik Dresden AG — Rev.1.00 All rights reserved.

(1) 12 of 21 ZSLS7031 Isolated and Non-isolated Flyback LED Driver with Active PFC 2.7 Output Over-Voltage Protection Over-voltage protection of the output (OVP) is achieved by connecting a resistor network from the auxiliary winding to the FB pin. By sensing the voltage of the auxiliary winding, which is proportional to the output voltage, the ZSLS7031 detects when there is an open circuit condition on the secondary side and consequently reduces the switching action to a minimum burst mode. The threshold voltage for the FB pin is typically 1.25V. Care must be taken that the high ripple current bursts do not lead to an overshoot of the output capacitor’s rated voltage. This can be accomplished by a Zener diode in parallel, rated slightly lower than the output capacitor’s nominal voltage or a reasonable discharge resistor. The ZSLS7031 will recover to normal operation when the open-circuit condition has been corrected. Figure 2.4 2.8 Output Over-Voltage Protection Output Over-Current Protection (OCP) If the output of the circuit is suddenly shorted, the resulting over-current condition is detected on the primary side and the converter will shut off for 30 cycles when the over-current comparator has switched after time tblank (see specification 1.3.7) has elapsed. 2.9 Under-Voltage Lock Out (UVLO) If the input voltage on the VCC pin falls below the under-voltage threshold VTH_D (see specification 1.3.2), the under voltage lock out (UVLO) will be triggered. In this event, the device will stop operating until the VCC voltage rises above the startup threshold VTH_S (see specification 1.3.1), at which point the device will start again.

At high input voltages, the slope of the input current is quite steep, and therefore it will overshoot the target value by more than it would at low input voltage conditions. Therefore, under wide input voltage conditions, and without additional compensation, the output power varies over the full input voltage range, 85VAC to 265VAC, by about +/-5%. To further improve the line regulation, a simple compensation circuit can be added as shown in Figure 3.1 and Figure 3.2 with components R4, R12, R13, R14, R15, and C9. 3.3 Transformer Design The transformer design is described in a separate application note ZSLS7031_AN_TransformerDesign.pdf supported by a calculation spreadsheet.

As for all switching power supplies, especially those providing high current and using high switching frequencies, layout is an important design step. If the layout is not well-designed, the regulator could show instability as well as EMI problems. For additional information, refer to the ZMDI application note PCB Layout Design Guidelines for LED Driver Circuits available at www.zmdi.com/products/led-drivers/. Components such as R4, RCS, R6, R7, R2, C2, C5, etc., that are connected to the ZSLS7031 as well as the bypass capacitors should be mounted as close to the ZSLS7031 as possible. Switching signal traces should be kept as short as possible and not be routed in parallel to one another so as to prevent coupling. Power ground and signal ground should be separated, and the traces of power ground should be kept as short as possible. Figure 3.3 shows, as an example, the layout of the ZSLS7031 Demonstration Board comprising a 20W isolated flyback design on a 28mm x 71mm PCB area. Note: This board’s component labels are different from those in previous schematics and equations. Figure 3.4 shows the corresponding circuit diagram.
