Brief Description
The KTD251 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 KTD251 to drive up to 36V output (10 LEDs in
series), up to 24V using KTD251B (6 LEDs in series) or up
to 19V using KTD251C (5 LEDs in series). Alternatively,
KTD251 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 KTD251,
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 KTD251 is available in a RoHS compliant 6-lead
TSOT23 package.
