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

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 (EN) pin. The PWM signal can be as fast as 50kHz because the LM2707 has a fast turn-on time. In addition to LED-drive.
