Brief Description
The KTD2801/A/B is a versatile constant current LED
driver with a high efficiency DC-DC step up “boost”
converter architecture. The low-side power MOSFET and
high-side diode are integrated in the device, minimizing the
total number of external components. Unique technology
and high 0.52A current limit allow KTD2801 to drive up to
36V output (10 LEDs in series), or KTD2801A 30V output
(8 LEDs in series) or KTD2801B 24V output (6 LEDs).
Alternatively, the KTD2810 can deliver 40mA total current
for two parallel strings of up to 6 series LEDs. It can also
maximize the current capability while achieving high
conversion efficiency. The optimized 1MHz switching
frequency results in small external component size. The
driver is equipped with an internal decoder that allows
digital FB control dimming for 256-step (8-bit) current
programming and can also be used for PWM dimming with
a one-line control signal.
Various protection features are built into the KTD2801/A/B,
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 device is available in a RoHS compliant 6-lead
TDFN22 package and 6-lead Thin SOT-23 package
