General Description
The Supertex HV826 is a high voltage driver designed for
driving EL lamps. The input supply voltage range is from 1.8V
to 3.5V. The device uses a single inductor and a minimum
number of passive components. The nominal regulated output
voltage that is applied to the EL lamp is ±80V. The chip can be
enabled/disabled by connecting the resistor on the RSW-Osc
pin to VDD/GND.
The HV826 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 RSW-Osc pin and the VDD supply pin. The EL
lamp driver frequency is set by an external resistor connected
between REL-Osc pin and the VDD pin. An external inductor
is connected between the LX pin and VDD pin. A 0.01-0.1µF
capacitor is connected between the CS pin and GND. The EL
lamp is connected between the VA pin and the VB pin.
The switching MOSFET charges the external inductor and
discharges it into the capacitor at the CS pin. The voltage at
CS will start to increase. Once the voltage at CS reaches a
nominal value of 80V, the switching MOSFET is turned OFF
to conserve power. The output pins VA and VB are configured
as an H bridge and are switching in opposite states to achieve
160V peak-to-peak across the EL lamp.
