Brief Description

The KTD2531 is a versatile constant current LED driver

with a high efficiency DC-DC step up “boost” converter

architecture. The low-side power MOSFET is integrated in

the device, minimizing the total number of external

components. Unique technology and high 800mA current

limit allow KTD2531 to drive up to 36V output (10 LEDs in

series), up to 24V using KTD2531B (6 LEDs in series) or

up to 19V using KTD2531C (5 LEDs in series).

Alternatively, KTD2531 can deliver 160mA total current

with 3 series LEDs per string. It can also maximize the

current capability while achieving high conversion

efficiency. The optimized 0.9MHz and 1.1MHz switching

frequencies result in small external component size. The

driver allows a wide range of PWM dimming frequencies

through the EN pin.

Various protection features are built into the KTD2531,

including cycle-by-cycle input current limit protection, LED

open-circuit (output over voltage) protection and thermal

shutdown protection. The leakage current in shutdown

mode is less than 1μA.

The KTD2531 is available in a RoHS compliant 6-lead

TSOT23 package.
