PM6600

Overview

The PM6600 is an LED lighting driver manufactured by STMicroelectronics, designed to drive six rows of LEDs at a constant current of 30 mA. It integrates a boost converter topology to manage voltage requirements for LED arrays. The component is housed in a 24-pin HVQCCN (VFQFPN) package with dimensions of 4 mm. It operates within a maximum ambient temperature of 85 °C and complies with RoHS standards.

Feature Summary

• Integrates a boost converter for efficient LED string driving
• Supports independent control of six distinct LED rows
• Provides constant current regulation for consistent brightness

Applications

• LED backlighting systems
• General LED illumination modules
• Compact lighting fixtures requiring integrated driver solutions

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the part number PM6600TR appears in databases associated with both ON Semiconductor and STMicroelectronics. Ensure the selected component matches the STMicroelectronics specification for a 6-row, 30 mA LED driver with boost functionality in a QFN-24 package. Confirm package details and electrical parameters against official datasheets before integration.

Selection Notes

Select this component for applications requiring a compact solution for driving multiple LED rows with integrated power conversion. The choice depends on the need for a single-chip boost driver that simplifies board layout by eliminating external inductors or complex discrete circuits. Consider the thermal performance limits and package size constraints relative to the target enclosure design.
