ZSP4412A
Zywyn
Electroluminescent Lamp Driver
Super Low Standby Current
General Description
Features
• +2.2V to +3.6V battery operation
• 50nA maximum standby current (10nA typical)
• High voltage output typical 160V
• External oscillator required
• Enable control pin
The ZSP4412A is a high voltage output DC-AC converter
that can operate from a +2.2V to +3.6V power supply. The
ZSP4412A is designed with our proprietary high voltage
BiCMOS technology and is capable of supplying up to
PP
250V signals, making it ideal for driving small electrolu-
PP
minescent lamps. The device features 10nA (typical)
standby current, for use in low power portable products.
An inductor is used to generate the high voltage, and an
external oscillator is needed as a clock source. The
ZSP4412A is offered in an 8-pin narrow SOIC package or
an 8-pin MSOP package. For delivery in die form, please
consult the factory.
