Brief Description
KTZ8866 is the ideal power solution for LED backlighting
and LCD bias power of medium size panels. It integrates a
step-up converter for LED backlighting, a step-up converter
with LDO and inverting charge pump for LCD bias power,
resulting in a simpler and smaller solution with fewer
external components. High switching frequency allows the
use of a smaller inductor and capacitor. Its input operating
range is from 2.7V to 5.5V, accommodating 1-cell lithium
ion batteries or 5V supply.
The LED driver’s six regulated current sinks can regulate
up to 30mA with its maximum boost output voltage up to
40V. 11-bit linear or exponential ILED resolution can be
obtained over I2C or PWM dimming. For additional
flexibility, PWM dimming offers wide range frequency and
duty cycle to support Content Adaptive Brightness Control
(CABC).
The LCD bias power section includes a step-up converter,
LDO and an inverting charge pump to generate dual
outputs, OUTP and OUTN, whose voltages can be
programmed via an I2C interface. By integrating
synchronous rectification MOSFETs for the step-up
converter and charge pump, the KTZ8866 maximizes
conversion efficiency up to 85.
Various protection features are built into KTZ8866,
including inductor current limit protection, output short
circuit protection, output over-voltage protection, LED fault
(open or short) protection and thermal shutdown
protection.
KTZ8866 is equipped with I2C interface for various controls
and status monitor.
KTZ8866 is available in a RoHS and Green compliant 28-
ball 1.73mm x 2.92mm x 0.62mm WLCSP package.
