LED Driver with Built-in PWM Signal Generation Circuit - BD18351EFV-M
BD18351EFV-M is an LED driver with built-in 1ch boost controller. It is an optimal IC for LED drive for head lamp/DRL, tail lamp and turn lamp capable of realizing boost and buck boost with high-side detection of LED current setting against output voltage. Further, cost saving and downsizing of the set can be realized, since it contains CRTIMER which enables PWM dimming without microcomputer for applications requiring PWM dimming of DRL, etc.
