BD9488F Boost 1channel white LED driver

BD9488F is a high efficiency driver for white LEDs and designed for large LCDs. This IC is built-in a boost DCDC converters that employ an array of LEDs as the light source. BD9488F has some protect function against fault conditions, such as the over-voltage protection (OVP), the over current limit .

BD9488F Features

* Current mode DCDC converter

* Vout discharge circuit as shutdown

* LED protection circuit (OPEN protection, LED OCP protection)

* LED protect detection as small PWM dimming signal

* Over-voltage protection (OVP) for the output voltage.

* Adjustable soft start time constant
