Overview
The BD92111F-GE2 is a white LED driver designed for large screens, utilizing PFC direct-connected current resonance topology. It features a single output channel with an operating input voltage range of 8V to 18V and a maximum switching frequency of 0.2MHz. The device operates within a temperature range of -40°C to 85°C and is housed in an SOP18 package measuring 11.2x7.8mm with a thickness of 2.01mm. It supports 20V high-rating processes and includes adjustable soft start and timer functions.
Feature Summary
- Implements push-pull control with current and voltage feedback driven by frequency adjustment.
- Provides over-voltage protection and under-voltage detection for IC power lines.
- Supports shift to save mode via STB terminal and burst control through external PWM signals.
Applications
- White LED drivers for large screen displays
Procurement Notes
This component is designated as Not Recommended for New Designs (NRND) and is produced solely to support existing customers. It is not available for new design implementations. Verification of the specific suffix GE2 is required to confirm the tape and reel packaging configuration and RoHS compliance status before integration into any legacy maintenance or replacement projects.
Selection Notes
Engineers should avoid selecting this part for new product development due to its NRND status. The device is restricted to supporting existing customer bases only. Designers requiring similar functionality must identify alternative components from the manufacturer's current portfolio that offer active production status and long-term supply availability for future manufacturing cycles.
Part Context
The BD92111F-GE2 belongs to the BD92111 series of LED lighting drivers manufactured by ROHM Semiconductor. It is specifically engineered for applications requiring PFC direct connection capabilities. The device integrates control logic with power switching elements in an SOP18 package, targeting efficiency and reliability in large-scale display illumination systems.
Replacement Considerations
No public confirmed substitute part numbers are documented for this component. Due to the NRND status and specific PFC direct-connected current resonance architecture, direct replacements require careful evaluation of electrical compatibility and functional equivalence by system engineers.
