General Description

Features

Processed with HVCMOS^®technology

1.0V to 1.6V supply voltage

DC to AC conversion

The Supertex HV824 is a high voltage driver designed to drive EL

lampswithcapacitiveloadsof2nFto15nF. Theinputsupplyvoltage

range is 1.0V to1.6V. The device uses a single inductor and a

minimum number of passive components. Typical output voltage

applied to the EL lamp is 120V to 150V peak-to-peak. The HV824

can be enabled/disabled by connecting the R_SWresistor to

Adjustable output lamp frequency to control lamp color,

lamp life, and power consumption

enables the IC when it is at logic low.

Adjustable converter frequency to eliminate harmonics and

optimize power consumption

The HV824 has two internal oscillators, a switching MOSFET, and

a high voltage EL lamp driver. The frequency for the switching

MOSFET is set by an external resistor connected between the

R_sw-oscpin and the V_DDpin. The ELlamp driver frequency is set by

an external resistor connected between the R_EL-oscpin and the V_DD

pin. AnexternalinductorisconnectedbetweentheL_xand V_DDpins.

A 0.01µF to 0.1µF capacitor is connected between C_sand GND

pins. The EL lamp is connected between V_Aand V_B.

Enable/disable function

Low current draw under no load condition

Applications

Pagers

The switching MOSFET charges the external inductor and dis-

charges it into the 0.01µF to 0.1µF capacitor at C_s. The voltage at

C_Swill start to increase. Once the voltage at C_sreaches a nominal

value of 75V, the switching MOSFET is turned OFF to conserve

power. The outputs V_Aand V_Bare configured as an H-bridge and

are switching in opposite states to achieve a maximum voltage of

180V peak-to-peak across the EL lamp.
