AN30251A-VB

Overview

The AN30251A-VB is an LED driver controller manufactured by Panasonic Electronic Components. It operates as a DC-DC step-up (boost) converter designed for single-output applications. The device supports dimming currents of 20mA and 100mA. It is housed in a compact 16-QFN package with dimensions of 4.2x3.2 mm. The component functions within a supply voltage range of 3V to 5.5V, providing efficient control for LED lighting systems.

Feature Summary

Integrated DC-DC boost controller architecture for LED power management
Supports multiple dimming current levels including 20mA and 100mA
Compact surface-mount packaging suitable for space-constrained designs

Applications

LED lighting systems requiring boost conversion
Portable electronic devices with LED indicators
General illumination circuits utilizing single-output LED drivers

Procurement Notes

Verify the specific suffix 'VB' against official Panasonic documentation to confirm pinout and thermal characteristics. Ensure compatibility with the intended PCB footprint, specifically the 16-QFN 4.2x3.2mm outline. Confirm that the 3V to 5.5V input range aligns with the system power supply design before procurement.

Selection Notes

Select this component when a compact boost controller is required for LED applications. The 16-QFN package offers a small form factor compared to larger alternatives. Verify that the required dimming current specifications match the 20mA or 100mA capabilities provided by this specific part number variant.

Part Context

This component belongs to Panasonic's portfolio of power management integrated circuits, specifically targeting LED driver solutions. It represents a specialized IC category distinct from passive components like resistors or mechanical switches found in other Panasonic lines. The device focuses on active voltage regulation for optoelectronic loads.
