Brief Description
The KTZ8812 is a dual output power supply IC used in
portable appliances where both a positive and negative
supply is required. The positive and negative output rails
provide bias supplies for TFT LCD panels, OPA, Audio
Amplifiers, DAC etc. The device only requires a single
inductor, thereby minimising the total PCB area.
It features an integrated step-up DC-DC converter with
input voltage range from 2.7V to 5.5V. An LDO and charge
pump generate dual regulated outputs, whose voltages
can be programmed via an I2C compatible interface.
Optimized step-up, LDO and charge pump converters
maximize conversion efficiency, exceeding 85.
KTZ8812 integrates all compensation and soft-start
circuitry, which results in a simpler and smaller solution
with much fewer external components. High switching
frequency (1.8MHz) allows the use of a smaller inductor
and capacitor to further reduce the solution size.
The I2C compatible interface allows control of the positive
and negative outputs from +4.0V to +6.3V and from -4.0V
to -6.3V, respectively, as well as programming additional
registers on the device.
KTZ8812 is available in a RoHS compliant 15-bump
2.2mm x 1.45mm x 0.62mm WLCSP.
