LM2707 Datasheet (National Semiconductor) - Inductive-Boost Series LED Driver

LM2707, Inductive-Boost Series LED Driver

The LM2707 is a magnetic boost regulator specifically designed for white LED drive applications.

Tightly regulated LED currents, exceptional LED brightness uniformity, and very high LED-drive power efficiency ( > 80%) can all be achieved by stacking the LEDs in series between the www.DataSheet4U.com

LM2707 Features

* 18V output capability, PFM regulation, and a high-current switching transistor (400mA peak). These characteristics allow the part to drive a series string of 2-to-4 LEDs with forward currents between 0 and 40mA. LED brightness can be adjusted dynamically simply by applying a PWM signal to the enable
