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.
