Overview
The BD94062F-E2 is a single-channel white LED driver IC designed for large LCD backlight applications. It utilizes a buck topology to regulate current, supporting an input voltage range of 10.5 V to 35 V. The device delivers a maximum output current of 15 mA and operates at a switching frequency of 150 kHz. It features PWM and analog dimming capabilities, along with open LED protection. The component is housed in a SOP-16 package and functions within a temperature range of -40°C to +105°C.
Feature Summary
- Integrates a buck-type DC/DC converter optimized for driving white LEDs in large LCD panels.
- Supports both PWM and analog dimming methods for precise brightness control.
- Includes built-in protection mechanisms such as open LED detection to ensure system reliability.
Applications
- Backlight drivers for large LCD displays
- White LED lighting systems requiring buck topology
- Industrial display modules
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the SOP-16 package dimensions align with the PCB footprint. Confirm RoHS compliance status through official documentation before finalizing procurement specifications.
Selection Notes
Select this component when a low-current buck converter is required for large LCD backlighting. It is suitable for designs needing integrated protection against open LED faults. Consider the 150 kHz switching frequency for inductor sizing and the wide operating temperature range for industrial environments.
Part Context
This part belongs to ROHM Semiconductor's LED lighting driver IC series. These devices are engineered for efficient power management in display applications. The BD94062F-E2 specifically targets high-reliability needs in large format screens, distinguishing itself from boost-type drivers used in different LED configurations.
