IS31LT3352-V2GRLS2-TR

Overview

The IS31LT3352-V2GRLS2-TR is an LED driver regulator IC featuring a step-down (buck) topology. It operates as a continuous mode inductive converter designed to drive single or multiple series-connected LEDs efficiently. The device integrates an internal switch and supports both PWM and analog dimming methods. Key electrical parameters include a 750mA output current capability, a switching frequency of 1MHz, and an 8-SOP surface-mount package.

Feature Summary

• Integrates an internal power MOSFET for compact design
• Supports combined PWM and analog dimming control
• Utilizes step-down buck topology for efficient voltage conversion

Applications

• General lighting applications
• Single LED driving circuits
• Multiple series-connected LED arrays

Procurement Notes
