BD9486F-GE2

Overview

The BD9486F-GE2 is a single-channel boost-type white LED driver IC designed for large LCD backlights. It integrates a current-mode DC/DC converter with an operating frequency of 150 kHz. The device supports a supply voltage range of 9 V to 18 V and features adjustable output voltage. Key specifications include a maximum operating temperature of +85 °C and a minimum of -40 °C. It utilizes a 16-pin SOP package with dimensions of 10.0 mm x 6.20 mm. The IC supports both analog dimming (0.2 V to 3.0 V) and PWM dimming, offering flexible control options for backlight applications.

Feature Summary

• Integrates a high-efficiency boost DC/DC converter with current mode control for stable LED driving.
• Includes comprehensive protection circuits such as over-voltage protection (OVP), over-current limit protection (OCP), and over-boost protection (FBMAX).
• Supports wide-range analog dimming from 0.2 V to 3.0 V alongside PWM dimming capabilities for precise brightness control.

Applications

• Large LCD panel backlighting systems
• White LED driver circuits for display modules
• Industrial display units requiring robust fault protection

Procurement Notes

Verify the specific suffix 'GE2' to ensure compliance with RoHS standards and lead-free manufacturing requirements.
