Overview
The LM2754SQX is an integrated low-noise, high-current switched capacitor DC/DC converter designed for camera flash applications. It features four independent output channels capable of delivering up to 800mA total current. The device operates with a switching frequency of 1MHz and provides a regulated voltage output range of 4.7V to 5.1V. It includes time-out protection to prevent thermal damage during extended operation. The component is housed in a compact 24-WQFN package.
Feature Summary
- Integrated switched capacitor topology for efficient charge pumping
- Four independent output channels for multi-LED arrays
- Built-in time-out protection mechanism
- Low noise design suitable for sensitive camera modules
Applications
- Camera flash LED drivers
- Mobile phone lighting systems
- Compact imaging devices
- High-current LED arrays
Procurement Notes
Verify the specific suffix 'SQX' against the official Texas Instruments datasheet to confirm pinout compatibility and electrical specifications. Ensure that the 24-WQFN package dimensions match the target PCB footprint. Confirm that the device lifecycle status aligns with long-term production requirements before finalizing procurement plans.
Selection Notes
Select this component when a low-profile solution for high-current flash lighting is required. The switched capacitor architecture eliminates the need for external inductors, saving board space. Consider the 1MHz switching frequency for EMI management and the maximum output current limits relative to the connected LED load configuration.
Part Context
This part belongs to the Texas Instruments family of LED driver ICs optimized for portable electronics. It complements other linear and buck converters by providing a specialized charge pump solution for flash applications where size and efficiency are critical constraints.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs using direct parameter comparison if alternative sources are considered.
