Brief Description
The KTD2159 is a TFT-LCD power supply IC for small and
medium size displays for smartphones and tablets. The
positive and negative output rails provide bias supplies for
TFT LCD panels via the Source Driver IC. The device only
requires a single inductor, to reduce the total PCB area.
It features a highly integrated step-up DC-DC converter
with wide input voltage range from 2.7V to 5.5V. An LDO
and charge pump generate dual outputs from +4.0V to
+6.3V (100mV/step) and -4.0V to -6.3V (100mV/step),
whose voltages can be programmed via external resistors.
Optimized step-up, LDO and charge pump converters
maximize conversion efficiency, exceeding 85.
KTD2159 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 external resistors allows to set the positive and
negative outputs from +4.0V to +6.3V and -4.0V to -6.3V,
respectively.
KTD2159 is available in a RoHS compliant 15-bump
2.2mm x 1.45mm x 0.62mm WLCSP and 14-lead TDFN
2.5 x 3.0 x 0.75mm.
