AP4312QK6TR-G1

Overview

The AP4312QK6TR-G1 is an automotive-grade CC/CV controller for switch-mode power supplies, designed for 6-pin automotive systems with input voltages from 1.7V to 18V. It features a fixed 1.21V reference and 70mV current sense threshold. The device operates at a minimum cathode current of 0.18mA and supports SMD/SMT mounting in a compact package measuring 3.1mm x 1.7mm x 1.3mm. It holds AEC-Q100 qualification.

Feature Summary

• Automotive-qualified voltage regulation for 6-pin automotive architectures
• Integrated constant current and constant voltage control loop
• Low operating current capability for efficient power management

Applications

• Automotive lighting systems
• Vehicle interior electronics power regulation
• Compact automotive DC-DC converter designs

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm AEC-Q100 compliance status for specific automotive grade requirements. Check moisture sensitivity level handling procedures prior to assembly. Ensure the ordering suffix matches the required reel packaging specifications for surface mount integration.

Selection Notes

Select this controller for applications requiring precise voltage regulation within automotive environments. The low input voltage start-up capability suits battery-powered systems. Verify thermal performance against the specified package dimensions. Ensure the 1.21V reference aligns with downstream load requirements.

Part Context

This component belongs to the AP4312 series of specialized power management integrated circuits. It functions as a dedicated controller rather than a simple shunt regulator. The QK6 suffix indicates specific automotive qualification and tape-and-reel packaging configuration suitable for high-volume manufacturing processes.
