Brief Description
The KTD2151 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 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.
KTD2151 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.
KTD2151 is available in a RoHS and Green compliant 15-
bump 2.2mm x 1.45mm x 0.62mm WLCSP and 14-lead
TDFN 2.5 x 3.0 x 0.75mm.
