High Voltage EL Lamp Driver CPC6826 Features • • • • • • • • 1.8V to 3.5V Supply Voltage DC to AC Conversion Adjustable Output Frequency Adjustable Switch Frequency Output Voltage Regulation Enable/Disable Function Split Power Supply Capability < 100nA Shutdown Current Description Clare’s CPC6826 is an electroluminescent (EL) lamp driver that is designed for applications operating with an input supply voltage range of 1.8V to 3.5V. The CPC6826 can also be used in a split-supply configuration, which enables the designer to specify operation with an input voltage as low as 1.5V. Only five passive, external components are required: an inductor, a capacitor, and a diode to complete the boost switcher circuit; and two resistors to set the frequency of the two internal oscillators. These few components and the CPC6826 together generate the typical 170VP-P AC signal required to drive an EL lamp. The configuration of the CPC6826, with designer access to important components, allows maximum design flexibility for optimal efficiency and brightness.

The device is capable of driving lamp panels ranging from 1 in2 to 5 in2. The CPC6826 IC main block architecture is made up of two independent oscillators, which control the switching of a power MOSFET and an H-bridge. Adjustment of two external resistors, RSW and REL, sets the frequencies of the oscillators, thus allowing the designer to maximize efficiency and to increase the brightness of the lamp. To conserve supply power and extend battery life, the CPC6826 automatically shuts down the switcher circuit whenever switcher output power exceeds load requirements. Supply power can also be conserved manually by disabling the switching circuit: pull pin 2, RSW, to ground. 4.2 Regulation The circuit configuration is based on simple boost converter topology. This method provides excellent efficiency, minimizes loss of energy, and allows smaller components to be used in the design. Only a few passive components (an inductor, a capacitor, two resistors, and a diode) are required to complete the simple boost switcher circuit. R00C When power is applied to VDD, the internal feedback voltage VSEN is less than VREF causing the comparator output to go low, which enables the switching power MOSFET oscillator. When turned on, the internal low impedance switching MOSFET causes current to flow through the external inductor. With current flowing in the inductor, the switching MOSFET is turned off causing a flyback voltage to develop across the inductor. As the inductor's flyback voltage increases to a level greater than a diode drop above the voltage across the capacitor on the CS pin, charge stored in the inductor is transferred into the COUT capacitor. This operating cycle continues until the VSEN voltage is above the VREF in which case the comparator disables the Switch Oscillator. The internal high voltage H-Bridge section is enabled by external resistor REL at pin 3 and VDD on pin 1. The H-bridge operation is controlled by output oscillator waveforms driving H-bridge high-side and low-side MOSFETs. Selecting the value of REL allows the designer to set the frequency of the internal oscillator to meet design requirements. By alternately switching the terminals of the lamp between high voltage supply and ground the 180VP-P potential develops across the EL lamp. www.clare.com 9 CPC6826 4.3 Switch Oscillator Frequency An external resistor connected between pin 2, RSW, and pin 1, VDD, controls the frequency of the Switch Oscillator. Switching frequency increases as the resistor value decreases. For resistor value selections, please refer to the typical characteristics graph: Switching Frequency vs. Switch Resistor. Note that switch accuracy is +/-20% due to the internal RC network. CPC6826 Switching Frequency vs. Switch Resistor 1000 Switching Frequency (KHz) 4.4 Switcher Duty Cycle Clare’s CPC6826 driver is designed to generate a fixed duty cycle with a nominal 88% on-time. In addition, this circuit generates an adjustable converter frequency via RSW to turn on and off the high voltage power MOSFET. This drive method helps to eliminate RFI that can cause problems in portable wireless devices. The waveform on pin 5 (LX) shows a typical switch oscillator frequency of 79.6KHz. 100 10 1 100 1000 10000 CH1: 50V/Div Time: 2μs/Div Frequency = 79.6KHz RSW = 560KΩ REL = 1MΩ LX = 220μH EL Lamp = 1.6 in2 10 www.clare.com R00C CPC6826 4.5 Output Oscillator Frequency Setting the output oscillator frequency is accomplished by connecting an external resistor between pin 3, REL, and pin 1, VDD. The output oscillator frequency increases as the resistor value decreases. For resistor value selections refer to the typical characteristics graph: Output Oscillator Frequency vs. REL Resistor. The switching frequency range is 60Hz to 1000Hz, with an accuracy of +/- 20%. Note that higher EL frequencies draw more current from the battery. In addition to this, the color of the EL lamp and the light intensity are also dependent on the frequency. ranging from 0.01μF to 0.1μF with a working voltage of 100V. Ceramic capacitors come in 0805 or 1206 size with an X7R temperature coefficient. If the application requires higher stability over temperature, use a capacitor with a COG or NPO temperature coefficient. 5.3 Inductor The inductor value depends on the specific application requirements. In general, inductor values for typical application circuits range from 100μH up to 1mH. The smaller value inductors are well suited to drive larger lamp sizes due to their inherent high current handling capability. Note that when inductor value decreases, the switching frequency controlled by RSW should be increased to avoid inductor saturation. A 220μH Murata (LQH43MN221K03) inductor with 5.4-Ohm series DC resistance, 110mA rated current, and +/- 10% tolerance is recommended. For inductors with the same value and lower series DC resistance, RSW may have to be adjusted to avoid saturation. Murata offers the LQH43 series from 100μH to 560μH in the 1812 package size. 5.4 REL Resistor The EL lamp frequency is controlled via an external resistor connected from pin 3, REL-osc, to pin 1, VDD. The lamp frequency increases as the value of REL decreases. Higher EL frequency will increase the current that is drawn from the battery and will decrease the voltage at pin 6, VCS. The color of the Lamp also depends on its frequency. The size of the resistor used in the application is 0603 with a tolerance of 1%. Smaller size resistors can be used to reduce board space consumed. 5.5 RSW Resistor The switching frequency of the converter is set by adjusting the value of resistor, RSW, which is connected between pin 2 and pin 1, VDD. The switching frequency increases as RSW decreases. Increasing the value of Rsw will decrease the switching frequency of the internal oscillator, which in turn decrease inductor current and VCS voltage at pin 6. The size of the resistor used in the application is 0603 with a tolerance of 1%. Smaller size resistors can be used to reduce board space consumed. Output Oscillator Frequency (Hz) CPC6826 Output Oscillator Frequency vs. REL Resistor 10000 1000 100 10 0.1 1 10 4.6 Enable/Disable Function This function can be implemented to manually enable or disable the CPC6826. The enable function is accomplished by connecting resistor RSW, on pin 2, and resistor REL, on pin 3, to VDD pin 1. To disable the CPC6826, connect the two resistors to GND. 5. External Component Description 5.1 Diode The application circuit lists fast-reverse-recovery diodes such as the 1SS400T1G in the SOD523 package, with a breakdown voltage of 100V and a forward current rating of 200mA. The typical voltage drop is 950mV at 25°C and the reverse recovery time, tRR, is 4nS. 5.2 Output Capacitor The value of the output capacitor, COUT, connected to pin 6, is based on the particular application circuit and is dependent on peak inductor current, inductor size, and the load. The application circuits give values R00C www.clare.com 11 CPC6826 6. Manufacturing Information 6.1 Soldering For proper assembly, the component must be processed in accordance with the current revision of IPC/JEDEC standard J-STD-020. Failure to follow the recommended guidelines may cause permanent damage to the device resulting in impaired performance and/or a reduced lifetime expectancy. 6.2 Washing Clare does not recommend ultrasonic cleaning or the use of chlorinated hydrocarbons.
