LT1937ESC6#TRMPBF

LED Driver IC Overview

The LT1937ESC6#TRMPBF is a high-efficiency boost DC-DC converter IC designed for LED driver applications. It operates with an input voltage range of 2.5V to 10V and provides a switch current capability of 320mA. The device features a fixed switching frequency of 1.2MHz and supports both analog and PWM dimming control methods. It is housed in a compact SC-70-6 surface-mount package and functions within a temperature range of -40°C to 85°C.

LED Driver IC Feature Summary

• Integrated synchronous boost topology for high efficiency
• Supports analog and pulse-width modulation dimming control
• Fixed 1.2MHz switching frequency minimizes external component size

LED Driver IC Applications

• LED backlighting systems
• Portable electronic devices requiring efficient step-up conversion
• Battery-powered lighting solutions

LED Driver IC Procurement Notes

Verify the specific suffix ESC6 corresponds to the SC-70-6 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the required 1.2MHz operating frequency and dimming interface specifications.

LED Driver IC Selection Notes

Select this component for designs requiring a compact solution for driving LEDs from a single-cell lithium battery or similar power source. The integrated synchronous rectifier offers superior efficiency compared to asynchronous alternatives. Verify that the load requirements align with the 320mA internal switch limit and that the input voltage stays within the specified operational window.

LED Driver IC Part Context

This part belongs to the LT1937 family of micropower LED drivers manufactured by Analog Devices. It is functionally related to other variants such as the LT1937ES5, which utilizes a TSOT-23-5 package. The ESC6 designation specifically identifies the smaller SC-70-6 footprint suitable for space-constrained portable applications.

LED Driver IC Replacement Considerations

LT1937ES5#TRMPBF serves as a direct functional alternative with identical electrical characteristics but utilizes a TSOT-23-5 package instead of SC-70-6. Designers must verify pinout compatibility and physical footprint differences before substituting.
