Max. 28.5V Output 2Strings (25mA/ch) White LED Driver - BD65B60GWL

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.
This IC features highly accurate current drivers with low differential current errors between channels, thus, reducing brightness spots on the LCD panel. Moreover, its small package is suited for saving space.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
