BD65B60GWL - White LED Driver

Description

BD65B60 is a white LED driver IC that integrates PWM step-up DC/DC converter with boost-capability of up to maximum 28.5V and current driver with drive capability of up to 25mA(Typ.) maximum setting.

Precise brightness can be controlled at wide ranges through the external PWM pulse input.

Features

  • High efficiency PWM step-up DC/DC converter fSW1 = 1.1MHz(Typ. ), fSW2 = 0.60MHz(Typ. ).
  • High accuracy & good matching current drivers (2ch).
  • Soft Start function.
  • Drives up to 8 LEDs in series per channel.
  • Lower input voltage range requirement (2.7V to 5.5V).
