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. | ||
