Драйверы систем светодиодного освещения LM3410XQMF/NOPB

Драйвер светодиода , 1 выход, повышающий, SEPIC, 2.7В-5.5В (Vin), 1.6МГц, 24В/2.8A, SOT-23-5

The LM3410XQMF/NOPB is a constant current boost and SEPIC LED Driver with internal compensation. The constant current LED driver is a monolithic, high frequency and PWM DC/DC converter in 5-pin. With a minimum of external components the LM3410 is easy to use. It can drive 2.8A typical peak currents with an internal 170mR NMOS switch. Switching frequency is internally set to 1.6MHz, 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 80nA. It utilizes current-mode control and internal compensation to provide high-performance over a wide range of operating conditions. Additional features include dimming, cycle-by-cycle current limit and thermal shutdown.
