Brief Description
The KTD2511 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. High 1.2A current limit and 14V or 19V OVP
allow the KTD2511D/C to drive numerous parallel strings
of 3 or 5 LEDs in series, with KTD2511D or KTD2511C,
respectively. KTD2511 can deliver 260mA total current
with 3 series LEDs per string. It can also maximize the
current capability while achieving high conversion
efficiency. The optimized 1.0MHz switching frequency
results 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 KTD2511,
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 KTD2511 is available in a RoHS compliant 6-lead
TSOT23 and 8-lead TDFN22 package.
