LED Driver IC datasheet and documents for LYT3325D-TL

LYT3325D-TL

LED Driver IC Overview

The LYT3325D-TL is a single-stage LED driver IC from the LYTSwitch-3 family by Power Integrations. It integrates a high-voltage switching MOSFET and primary-side regulation for constant current output. The device supports power levels up to 20.4W with a breakdown voltage of 725V. It utilizes an SO-16B-14 package for surface mount installation. The component includes built-in protection features such as thermal shutdown and cycle-by-cycle current limit, designed for efficient AC-DC conversion in lighting applications.

LED Driver IC Feature Summary

Integrates primary-side regulation to eliminate optocouplers and secondary control circuitry
Includes a high-voltage switching MOSFET and novel on/off control state machine
Features frequency jitter technology to reduce electromagnetic interference emissions
Provides accurate output current regulation compensating for transformer variations

LED Driver IC Applications

Single-stage AC-DC LED drivers
Constant current LED lighting systems
Power factor corrected (PFC) LED applications

LED Driver IC Procurement Notes

Verify the specific suffix 'TL' indicates tape and reel packaging configuration. Confirm the 725V rating aligns with system requirements. Ensure compatibility with SO-16B-14 footprint during PCB layout. Check moisture sensitivity level handling procedures before assembly. Validate that the manufacturer designation matches Power Integrations specifications.

LED Driver IC Selection Notes

Choose this component for designs requiring integrated PFC and constant current regulation without secondary feedback loops. Consider the 20.4W power capability for medium-power LED fixtures. Evaluate the 725V breakdown voltage against peak line conditions. Assess the SO-16B-14 package constraints for thermal management and board space.

LED Driver IC Part Context

This part belongs to the LYTSwitch-3 series, which simplifies low-power CC LED driver design. The series introduces a control technique to handle external component variations and input voltage fluctuations. It combines a switched current source for self-biasing with hysteretic thermal shutdown for robust operation.
