General Description
The Supertex HV852 is a high voltage, low noise, inductorless
EL (electroluminescent) lamp driver. It is designed to drive EL
lamps of up to 1.5in2, with capacitive values up to 5.3nF over
an input voltage range of 2.4 to 5.0V. The HV852 converts a
low voltage DC input to a high voltage AC output across an
EL lamp. It uses a charge pump scheme to boost the input
voltage eliminating the need for an external inductor, diode,
and high voltage capacitor commonly found in conventional
topologies.
The charge pump circuit discharges its energy into an EL lamp
through a high voltage H-bridge. Once the voltage reaches
its regulated limit, it is turned off to conserve power. The EL
lamp is then discharged to ground and the H-bridge changes
state to allow the charge pump to charge the EL lamp in the
opposite direction.
