B0505S-2WR3

The B0505S-2WR3 from MORNSUN Power is a compact and efficient DC-DC converter, specifically a non-isolated module designed for converting a variable input voltage to a stable 5V output. Let's break down its key features and capabilities:

Function and Output:

• Converts a wide range of input voltages between 5V and 1500VDC to a regulated 5V output.
• Provides a maximum output current of 400mA, suitable for powering low-power electronics.
• Delivers a typical output ripple and noise of 60mV peak-to-peak, ensuring clean and reliable power supply.

Key Specifications:

• Package: SIP (19.65mm x 7.05mm x 10.16mm) - perfect for space-constrained designs.
• Efficiency: Up to 85% - minimizes power loss and heat generation.
• Isolation: None - electrically connected input and output (suitable for non-critical applications).
• Operating temperature range: -40°C to +85°C - works under varied environment conditions.

Additional Features:

• Short-circuit protection: Safeguards against accidental circuit failures.
• Overvoltage protection: Protects the converter from damage due to high input voltage.
• Overload protection: Limits output current to prevent overheating.
• No minimum load required: Operates efficiently even without a connected load.
