Max. 28.5V Output 2Strings(25mA/ch)
White LED Driver
BD65B60GWL
General 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.
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.
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)
Applications
Backlight for smartphones, games, digital video cameras,
digital single-lens reflexes, digital still cameras, digital photo
frames, Portable DVD player, etc.
