Brief Description
KTD3112/KTD3113 is the ideal power solution for white
LED backlighting used with medium to small size LCD
panels. It is a highly integrated step up DC-DC converter
with input voltage range from 2.7V to 5.5V, accommodating
1-cell lithium ion battery or 5V regulated supply.
KTD3112/3 integrates 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. High switching frequency (800kHz) allows
the use of a smaller sized inductor and capacitor.
Two regulated current sinks in KTD3112 and three sinks in
KTD3113 provide per channel 20mA/25mA (max.) factory
programmed current. With a 25V OVP, each string can
connect up to six LEDs in series, for a total of 12 or 18
LEDs in KTD3112 and KTD3113 respectively.
A PWM dimming control is included for wide output
dimming range. The device has an EN pin which enables
the IC.
Various protection features are built into KTD3112/3,
including cycle-by-cycle input current limit protection,
output over-voltage protection, LED fault (open or short)
protection and thermal shutdown protection. The leakage
current in shutdown mode is less than 1μA.
KTD3112/3 is available in a RoHS compliant and Green
16-lead 3mm x 3mm x 0.75mm ThinQFN or 9-lead 1.2mm
x 1.2mm WLCSP package.
