Brief Description
KTD2505R 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 1.2A current limit
allow KTD2505R to drive up to 38V output (10 LEDs in
series). It can also maximize the current capability while
achieving high conversion efficiency. The optimized
1.2MHz switching frequency results in reduced conduction
loss and small external component size. A single wire
interface is integrated which can be used for PWM
dimming or ExpressWire dimming in 32 steps.
Various protection features are built into KTD2505R,
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.
KTD2505R is available in an RoHS and Green compliant
6-lead TDFN 2x2mm package.
