Description
The MAX14521E is a quad-output high-voltage DC-AC converter that drives four electroluminescent (EL) lamps. The device features a 2.7V to 5.5V input range that allows the device to accept a variety of voltage sources such as single-cell lithium-ion (Li+) batteries.
Key Features
- a 2.7V to 5.5V input range that allows the device to accept a variety of voltage sources such as single-cell lithium-ion (Li+) batteries
- The lamp outputs of the device generate up to 300VP-P for maximum lamp brightness
- The MAX14521E utilizes a high-frequency spread-spectrum oscillator to reduce the amount of EMI/EFI generated by the boost-converter circuit
- The slew rate of the automatic ramp is set with 3 bits of resolution through the I2C interface and it is independent for each channel
- The MAX14521E features an audio auxiliary input AUX that modulates the EL output voltage and frequency for dynamic lighting effects
