LT3593EDC

LED Driver IC Overview

The LT3593EDC is a step-up DC/DC converter designed to drive up to ten white LEDs in series from a single Li-Ion cell. It integrates a high-efficiency switch and operates at a fixed 1MHz switching frequency. The device regulates LED current with high precision, eliminating the need for external balancing resistors due to the series connection topology. It features an output disconnect function and supports dimming control.

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., TRPBF vs TRMPBF) against the required packaging format. Confirm the manufacturer designation as Analog Devices Inc. or former Linear Technology. Ensure the package type matches the 6-DFN specification. Cross-reference the datasheet revision to ensure compatibility with design requirements.

LED Driver IC Selection Notes

Select this component when driving multiple white LEDs in series from a single-cell lithium battery source. It is suitable for space-constrained applications due to the small 6-DFN package. Consider the 1MHz frequency for minimizing passive component size. Verify input voltage range compatibility with the specific Li-Ion cell configuration used in the design.
