SNVS541H – OCTOBER 2007 – REVISED AUGUST 2016 LM3410, LM3410-Q1 525-kHz and 1.6-MHz, Constant-Current Boost and SEPIC LED Driver
With Internal Compensation
1 Features 3 Description The LM3410 and LM3410-Q1 constant current LED
driver are a monolithic, high frequency, PWM DC-DC
converter, available in 6-pin WSON, 8-pin MSOPPowerPadв„ў, and 5-pin SOT-23 packages. With a
minimum of external components the LM3410 and
LM3410-Q1 are easy to use. It can drive 2.8-A
(typical) peak currents with an internal 170-mО©
NMOS switch. Switching frequency is internally set to
either 525 kHz or 1.6 MHz, allowing the use of
extremely small surface mount inductors and chip
capacitors. Even though the operating frequency is
high, efficiencies up to 88% are easy to achieve.
External shutdown is included, featuring an ultra-low
standby current of 80 nA. The LM3410 and LM3410Q1 use current-mode control and internal
compensation to provide high-performance over a
wide range of operating conditions. Additional …
