IMP522 General Description
The IMP522 is a dual-output, high-voltage electroluminescent (EL) lamp driver. Either or both EL lamp driver outputs can be turned ON with the LMPSEL select pin. One EL lamp is connected between VA and VAB and the other is connected between VB and VAB. VAB is a common pin for both lamps. With an input supply voltage between 2.0V and 6.5V, the typical regulated lamp drive voltage is 220V peak-to-peak.
The device uses a single inductor and a minimum number of passive components: a storage capacitor, a fast recovery diode and two resistors to set the PWM and EL drive frequencies. These can be independently set to optimize brightness and minimize power consumption. RSW is connected between the RSW-OSC pin and the supply pin VDD to set the
frequency for the internal 4.0Ω switching MOSFET. The switch duty cycle is 88%. The EL lamp driver frequency is set by REL connected between theREL-OSC pin and the VDD pin.
Designed to minimize battery current drain, the IMP522 draws 2mA maximum. Apower-saving shutdown mode reduces current to 2µAmaximum.
The IMP522 is available in a compact 10-pin MicroSO package and in die form.
