Introduction

AI Translation

The MAX14514 is a high-voltage DC-AC converter ideal for driving two electroluminescent (EL) lamps. The MAX14514 features a +2.7V to +5.5V input range that allows the device to accept a wide variety of voltage sources, including single-cell lithium-ion (L1+) batteries. The lamp outputs of the device generate up to 300VP-P for maximum lamp brightness. The MAX14514 utilizes an inductor-based boost converter to generate the high voltage necessary to drive EL lamps and allows the use of a 220μH inductor to effectively drive total combined lamp sizes of up to 20nF. The MAX14514 uses a high-voltage full-bridge output stage to convert the high voltage generated by the boost converter to an AC waveform suitable for driving the EL panels. An external resistor controls the slew-rate of the rising and falling edges of the AC drive waveform to reduce audible noise output. The high-voltage outputs are ESD protected up to ±15KV Human Body Model, ±4KV IEC 61000-4-2 Air Gap Discharge, and ±4KV IEC 61000- 4-2 Contact Discharge. The MAX14514 features dimming/enable controls (DIM1, DIM2) for each output to allow the user to set the peak-to-peak output voltage with a PWM signal, a DC analog voltage, or a resistor connected from DIM_ to GND. The MAX14514 also provides a slow turn-on/-off feature that slowly ramps the output voltage applied to the lamp when enabled or disabled. The MAX14514 enters a low-power shutdown mode when the EN and DIM_ inputs are connected to GND. The device also features thermal shutdown if the die temperature exceeds +158°C (typ). The MAX14514 is available in a space-saving, 14-pin, 3mm x 3mm TDFN package and is specified over the extended -40°C to +85°C operating temperature range.
