STLD40DPMR

Overview

The STLD40DPMR is a DC-DC boost converter IC designed for LED driver applications, manufactured by STMicroelectronics. It operates with a supply voltage range of 3V to 5.5V and supports output voltages up to 37V. The device provides a regulated output current of 20mA per channel and features PWM dimming control. It is housed in an 8-QFN (3x3) package with exposed pad and is rated for operation within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Integrated boost topology for efficient LED power supply
• Regulated constant current output capability
• Supports pulse-width modulation dimming control

Applications

• Backlight driving for display modules

Procurement Notes

Verify the specific suffix 'MR' against official documentation to confirm tape-and-reel packaging specifications. Confirm current lifecycle status as the component may be discontinued or superseded by newer revisions. Ensure compatibility with existing board layouts regarding the 8-QFN footprint and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact boost converter solution is required for single-channel LED backlighting. Consider the 20mA output limit and 37V maximum output voltage constraints. Evaluate the 8-QFN package suitability for space-constrained designs requiring surface-mount assembly.

Part Context

This part belongs to the STLD40 series of LED drivers from STMicroelectronics. These integrated circuits are specialized for managing white LED power supplies in large displays. The series typically offers solutions for regulating LED current with high efficiency in small form factors.

Replacement Considerations

Check for the active revision STLD40DPUR as a potential alternative. Verify pinout and electrical parameter compatibility before substitution.
