MIC4834 Block Diagram Functional DescriptionOverviewThe MIC4834 is a high-voltage dual output EL driver with a peak-to-peak AC output voltage of 220V capable of driving two 3 in2 EL panels. The MIC4834 drives EL panels by converting a low DC input voltage to a high DC high output voltage using the boost regulator circuit and then alternating the high DC voltage across the EL panel using an H-Bridge. Input supply current for the MIC4834 is typically 152A. The high voltage EL driver has two internal oscillators to control the boost switching frequency and the H-bridge driver frequency. The internal boost oscillator frequency can be individually programmed through an external resistor to maximize efficiency and brightness of the EL panel. The H-bridge frequency is internally fixed at 225Hz to reduce external component count.R egulationReferring to Figure 1, power is initially applied to V DD. When the internal feedback voltage is less than the reference voltage, the internal comparator enables switching in the boost circuit. When the boost regulator is switching, current flows through the inductor into the switch. The switching MOSFET will typically turn on for 90% of the switching period. During the on-time, energyis stored in the inductor. When the switching MOSFET turns off, current flowing into the inductor forces the voltage across the inductor to reverse polarity. The voltage across the inductor rises until the external diode conducts and clamps the voltage at V OUT + V D1. The energy in the inductor is then discharged into the C OUT capacitor. The internal comparator continues to turn the switching MOSFET on and off until the internal feedback voltage is above the reference voltage. Once the internal feedback voltage is above the reference voltage, the internal comparator disables switching. The control circuit will continue to turn the MOSFET’s on and off to maintain a constant DC voltage at the CS pin.When the MIC4834 EL Driver is enabled, ELA and ELB will switch in opposite states with COM to achieve a 220V peak-to-peak AC output signal needed to drive the two EL panels.Switching FrequencyThe switching frequency of the converter is controlled by an external resistor (R SW ) between RSW and VDD. The switching frequency increases as the resistor value decreases. In general, the lower the switching frequency, the greater the input current is drawn to deliver more power to the output. Lowering the switching frequency can be used to drive larger panels. However, the switching frequency should not be so low as to allow the voltage at the switch node or the CS pin to exceed the absolute maximum voltage of those pins. For resistor value selections, see the “Typical Characteristics: Switching Frequency vs. SW Resistor” graph on Page 4 or use the equation below. The switching frequency range is 35kHz to 350kHz, with an accuracy of 20%.()Ω=M R 46(kHz)f SW SWEL FrequencyThe MIC4834 EL panel frequency is internally fixed at 225Hz.Enable FunctionThere are a few different ways to enable and disable the MIC4834. The boost regulator may be disabled by pulling the R SW resistor to ground. This turns off both the EL panels by cutting power to the device completely. The R SW resistor must be pulled to VDD to enable the boost oscillator. If it is not equal to VDD, then the frequency set by R SW will be different the programmed value.For individual panel control, the ENA and ENB pins can be used to enable ELA and ELB, respectively. Pulling ENA or ENB high (over 1.2V) or low (below 0.4V) willturn ELA and ELB panels on or off.Figure 2. EL Panel Waveform – 2 1 in2Figure 3. EL Panel Waveform – 2 2 in 2Figure 4. EL Panel Waveform – 2 3 in 2Application InformationThe MIC4834 is designed to use an inductance with a value between 100H to 330H. Choosing the right inductor is always a balance of size, inductance, efficiency, current rating and cost. A TDK (VLS4012T-221M) 220H inductor is recommended based on size, efficiency and current rating.Generally, the lower the inductance, the more current the inductor can handle. Lowering the inductance allows the boost regulator to draw more input current to deliver more energy every switching cycle. As a result, a lower inductance may be used to drive larger panels or brighten similar sized panels. However, caution is required as using a low inductance with a low switching frequency may cause the voltage at the switch node and the CS pin to exceed the absolute maximum rating. If the application uses a low input voltage (2.3V to 3V), then a lower value inductor, such as 100H, may be used in order to drive the EL panel at maximum brightness.DiodeThe diode must have a high reverse voltage (150V), since the output voltage at the CS pin can reach up to 130V. A fast switching diode with lower forward voltage and higher reverse voltage (150V), such as BAV20WS/BAS20W, can be used to enhance efficiency. Output CapacitorLow ESR capacitors should be used at the regulated boost output (CS pin), to minimize the switching output ripple voltage. The larger the output capacitance, the lower the output ripple at the CS pin. The reduced output ripple, at the CS pin, along with a low ESR capacitor improves the efficiency of the MIC4834 circuit. Selection of the capacitor value depends upon the peak inductor current, inductor size, and the load. The MIC4834 is designed for use with an output capacitance as low as 2.2nF. For minimum audible noise, the use of a C0G/NPO dielectric output capacitor is recommended. TDK and AVX offer C0G/NPO dielectric capacitors in capacitance up to 2.7nF at 200V to 250V voltage rating in 0805 size.EL Panel Terminals (ELA, ELB, COM)The two EL panels are connected from ELA to COM and ELB to COM. The ELA and ELB terminals are in phase with each other, while the COM is out of phase with both ELA and ELB. Since ELA and COM are out of phase, the high voltage generated by the boost regulator is alternated across ELA and COM by the H-Bridge. The frequency of each cycle is internally fixed at 225Hz. The alternating 220V peak-to-peak causes the EL panel to emit light. Similarly, the ELB and COM are also out of phase and allows a second EL panel to be driven at the same time. Both EL panels may operate independently from each other and do not have to be the same size. For component selection, Table 2 lists recommended values for various panel sizes up to a total of 6 in2 (For example, two 3 in2 panels). Driving overly large panels will result in a dimmer display, but will not cause damage to the device.Application CircuitFigure 6.
