BD9285F Boost 1channel white LED driver

BD9285F 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. BD9285F has some protect function against fault conditions, such as the over-voltage protection (OVP), the over current limit .

BD9285F 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) and low-voltage protection (SCP: short circuit protection) for the output voltage Vout Adjustabl
