Brief Description
KTD3134 is the ideal power solution for LED backlighting
and selfie flash in medium to large size LCD panels. It is a
highly integrated step-up DC-DC converter operating with
an input voltage from 2.7V to 5.5V, accommodating 1-cell
lithium ion batteries or 5V supply. It includes a high voltage
power NMOS, as well as two current sinks, resulting in a
simpler and smaller solution with fewer external
components. High switching frequency allows the use of a
smaller inductor and capacitor.
Each of the two regulated current sinks can regulate up to
29.8mA in backlight mode. With a maximum of 32V at the
output of the step-up converter, each string can connect up
to 8-LED in series for a 16-LED application.
KTD3134 is equipped with I2C interface for various
controls. For additional flexibility, PWM dimming with wide
range frequency and duty cycle is included to support
Content Adaptive Brightness Control (CABC).
KTD3134 also adds selfie flash function to the existing
backlight solution by boosting the sink current up to
59.6mA/Ch and integrating a flash timeout of up to 1.5sec.
Various protection features are built into KTD3134,
including cycle-by-cycle inductor current limit protection,
output overvoltage protection, LED fault (open or short)
protection and thermal shutdown protection.
KTD3134 is available in a RoHS compliant 12-ball 1.19mm
x 1.64mm WLCSP or a 16-lead 3mm x 3mm x 0.75mm
Thin-QFN package.
