DCP020503U

DCP020503U Description

The DCP020503U from Texas Instruments is a high-performance, 2W isolated DC-DC converter designed for industrial and commercial applications requiring stable, regulated power conversion. This compact surface-mount module delivers a fixed 3.3V output with a maximum current of 606mA, making it ideal for low-power embedded systems. With an input voltage range of 4.5V to 5.5V, it ensures compatibility with standard 5V power rails while maintaining 74% efficiency for optimized energy usage. The module features 1 kV isolation, enhancing safety and noise immunity in sensitive circuits. Its ultra-compact dimensions (18.1mm x 7.6mm x 2.7mm) and ROHS3 compliance make it suitable for space-constrained, environmentally conscious designs.

DCP020503U Features

• High Isolation Voltage (1 kV): Ensures robust protection against voltage transients and ground loops.
• Over-Temperature Protection (OTP): Safeguards the module from thermal overload, improving reliability.
• Wide Input Range (4.5V–5.5V): Supports fluctuating input voltages common in industrial environments.
• Compact & Lightweight: Minimal footprint (0.71" x 0.30") for dense PCB layouts.
