External/Internal DC DC Converters

EN63A0QA Description

The EN63A0QA from Intel's Enpirion® series is a high-efficiency, single-output DC-DC converter designed for commercial ITE applications. With an input voltage range of 2.5V to 6.6V and an adjustable output voltage of 0.6V to 5.4V, this compact converter delivers a robust 12A maximum output current while achieving an impressive 96% efficiency. Its surface-mount design and ultra-compact dimensions (11.0mm x 10.0mm x 3.0mm) make it ideal for space-constrained applications. Although marked as Obsolete, it remains a reliable choice for legacy designs due to its advanced protection features and compliance with RoHS and REACH standards.

EN63A0QA Features

• High Efficiency (96%): Minimizes power loss and thermal dissipation, enhancing system reliability.
• Comprehensive Protection: Includes Over-Current Protection (OCP), Over-Temperature Protection (OTP), Short-Circuit Protection (SCP), and Under-Voltage Lockout (UVLO) for robust operation.
• Compact Footprint: Small 0.43" x 0.39" size with a low-profile 0.12" height, suitable for high-density PCB layouts.
• Wide Input/Output Range: Supports flexible power supply configurations.
• Commercial-Grade Reliability: MSL 3 (168 Hours) moisture sensitivity ensures durability in manufacturing environments.
• Tape & Reel Packaging: Facilitates automated assembly processes.
