LM3410
525kHz/1.6MHz, Constant Current Boost and SEPIC LED
Driver with Internal Compensation
General Description
The LM3410 constant current LED driver is a monolithic, high
frequency, PWM step-up DC/DC converter in 5-pin SOT23,
6-pin LLP, & 8-pin eMSOP packages. With a minimum of ex-
ternal components the LM3410 is easy to use. It can drive
2.5A typical peak currents with an internal 160m
NMOS
switch. Switching frequency is internally set to either 525kHz
or 1.60MHz, allowing the use of extremely small surface
mount inductors and chip capacitors. Even though the oper-
ating frequency is high, efficiencies up to 88% are easy to
achieve. External shutdown is included, featuring an ultra-low
stand-by current of 80nA. The LM3410 utilizes current-mode
control and internal compensation to provide high-perfor-
mance over a wide range of operating conditions. Additional
features include dimming, pulse-by-pulse current limit, and
thermal shutdown.
