ROHM BD9486F-GE2 LED Driver IC, 9 → 18 V 16-Pin SOP16

The ROHM BD9486F series is a high-efficiency LED driver for white LEDs and designed for a large LCD panel. It has a boost DC-DC converter that employs an array of LEDs as the light source. This driver has some protective function against fault conditions, such as the over-voltage protection (OVP), the overcurrent limit protection of DCDC (OCP), LED OCP protection and over boost protection (FBMAX). Therefore, it is available for a fail-safe design over a wide range output voltage.

• Operating power supply voltage ranges between 9.0V and 18.0V
• Oscillator frequency of DCDC is 150kHz
• Operating current is 2.6mA
• Operating temperature ranges between -40°C and 85°C
• Adjustable soft start
• Wide range of analogue dimming ranges between 0.2V and 3.0V
• UVLO detection for the input voltage of the power stage

• Computer display
