Features

General Description

❏

Processed with HVCMOS^®technology

1.0V to 1.6V operating supply voltage

DC to AC conversion

The Supertex HV825 is a high voltage driver designed for driving

EL lamps typically up to 6nF. The input supply voltage range is

from 1.0V to 1.6V. The device uses a single inductor and a

minimum number of passive components. Typical output

voltage that can be applied to the EL lamp is 56V.

Output load of typically up to 6nF

Adjustable output lamp frequency

Adjustable converter frequency

Enable function

The HV825 can be enabled/disabled by connecting the R_SW-osc

resistor to V_DD/ground.

The HV825 has two internal oscillators, a switching bipolar

junction transistor (BJT), and a high voltage EL lamp driver. The

frequency for the switching BJT is set by an external resistor

connected between the R_SW-oscpin and the supply pin V_DD. The

EL lamp driver frequency is set by an external resistor connected

between R_EL-oscpin and the V_DDpin. An external inductor is

connected between the L_Xand V_DDpins. A 0.01 to 0.1µF, 100V

capacitor is connected between C_Sand ground. The EL lamp is

connected between V_Aand V_B.

Applications

❏

Pagers

Portable Transceiver

Cellular phones

Remote control units

Calculators

The switching BJT charges the external inductor and discharges

it into the 0.01 to 0.1µF, 100V capacitor at C_S. The voltage at C_S

will start to increase. The outputs V_Aand V_Bare configured as

an H-bridge and are switching in opposite states to achieve a

peak-to-peak voltage of two times the V_CSvoltage across the EL

lamp.
