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.
