Full-Bridge Controller For Piezoelectric TransformersLiquid-crystal Display (LCD) enclosures and cold-cathode
fluorescent lamps (CCFL) used in notebook computer
and portable electronic Displays are becoming increa-
singly narrow, generating the need for a low-profile
CCFL power supply. Recent advances in piezoelectric
transformers (PZTs) have made it possible to develop
smaller, more efficient, and safer backlight inverters for
portable Displays Piezoelectric transformers have
shown better performance than magnetic transformers
with respect to efficiency, EMI requirements, human
safety, and form factor. The MAX8785A is a full-bridge
CCFL Controller for piezoelectric transformer-based
backlight power supplies. The full-bridge topology pro-
vides a high-spectral purity sinusoidal drive that helps
the PZT convert electrical energy to mechanical and
back to electrical energy efficiently. By Maxim Integrated Products
