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 2.9V to 5.5V, accommodating 1-cell lithium ion batteries or 5V supply.<\/p>\n<p>The LED driver&#8217;s four regulated current sinks can regulate up to 30mA with its maximum boost output voltage up to 32V. 11-bit linear or exponential ILED resolution can be obtained over I<sup>2<\/sup>C or PWM dimming. For additional flexibility, PWM dimming offers wide range frequency and duty cycle to support Content Adaptive Brightness Control (CABC).<\/p>\n<p>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 I<sup>2<\/sup>C interface. By integrating synchronous rectification MOSFETs for the step-up converter and charge pump, the KTZ8864A maximizes conversion efficiency up to 85%.<\/p>\n<p>Various protection features are built into KTZ8864A, including inductor current limit protection, output short circuit protection, output over-voltage protection, LED fault (open or short) protection and thermal shutdown protection.<\/p>\n<p>KTZ8864A is equipped with I<sup>2<\/sup>C interface for various controls and status monitors.<\/p>\n<p>KTZ8864A is available in a RoHS and Green compliant 24-ball 1.72mm x 2.45mm x 0.62mm WLCSP package.<\/p>\n\t    <a href=\"https:\/\/pinakinnsoft.com\/kinetic\/wp-content\/uploads\/2026\/06\/KTD2511C-04a_typ_app_dia_02.png\" class=\"gallery-image\"
