Brief Description
KTD3122 is the ideal power solution for white LED
backlighting used with small to medium size LCD panels. It
is a highly integrated step-up converter accommodating
single cell lithium ion batteries or 5V regulated supply.
KTD3122 integrates a 30V power diode and a 30V power
MOSFET as well as compensation and soft start circuitry,
which results in a simpler and smaller solution with much
fewer external components. Adjustable switching
frequency (1MHz/500kHz) and OVP threshold (30V/24V)
allow the use of a smaller inductor and capacitor to further
reduce the solution size.
KTD3122 has two regulated current sinks up to 30mA per
string. With a maximum of 30V at the output of the step-up
converter, each string can connect up to 8 LEDs in series,
or up to 16 LEDs total.
KTD3122 is equipped with I2C interface for various
controls. For additional flexibility, wide frequency (100Hz to
100kHz) and duty cycle range (0.1 to 100 at 10kHz)
PWM dimming control is included and can support Content
Adaptive Brightness Control (CABC).
Various protection features are built into KTD3122,
including cycle-by-cycle input current limit protection,
output over-voltage protection, LED fault (open or short)
protection and thermal shutdown protection.
KTD3122 is available in a RoHS compliant and Green
16-lead 3mm x 3mm x 0.75mm Thin-QFN or 12-ball
1.21mm x 1.65mm x 0.62mm WLCSP package.
