Specifications

Key features of DCP020505U

• Integrated Isolated Power Solutions

  • It provides an isolation voltage of 1500VDC to achieve complete electrical isolation between input and output, and is very suitable for safe isolation between analog/digital circuits and power/signal interfaces.

• High efficiency and low power consumption operation

  • The internal high-frequency switching structure provides up to 85% energy efficiency, reduces heat dissipation pressure, and improves the overall power utilization of the system.

• Plug and play, simplify design

  • The package is standard DIP-8, which is compatible with traditional PCB design methods; the module contains a transformer and control circuit and can work without external devices.

• Stable output and wide operating temperature

  • It supports the industrial temperature range of -40°C to +100°C and can adapt to long-term operation in harsh environments. It has stable output voltage and low ripple, making it suitable for powering high-precision equipment.

• Comprehensive security protection mechanism

  • Built-in output short-circuit protection and thermal shutdown protection ensure that the output is automatically shut down under abnormal conditions to prevent damage to other circuits.

Typical application scenarios

Frequently Asked Questions (FAQ)

Q1: Does DCP020505U support hot-swap use?
In principle, hot-swap is not recommended. DCP020505U is an isolated DC-DC power module with multiple protection mechanisms such as short-circuit protection, overcurrent limiting and thermal shutdown, which can ensure the safety of the module itself under abnormal conditions. However, at the moment of power-on, the module may still generate a certain surge current. If hot-swapped while the system is powered on, it may cause electrical interference or impact to the input power supply or adjacent sensitive devices, thereby affecting system stability. To ensure system reliability, it is recommended to perform module plugging or replacement operations in a completely power-off state.

Q2: Can multiple modules be connected in series?
Direct series output is not recommended. Although multiple DCP020505U modules can be used to provide independent power supply for different isolated power domains and support parallel deployment in multi-channel isolation systems, their output is a fixed voltage (5V) and does not have a voltage balancing function, so direct series connection to increase the voltage is not recommended. If there is a need for series output (such as obtaining ±5V or 10V output), it is necessary to additionally design a voltage balancing circuit or adopt isolation measures to ensure that the load of each module is balanced. In addition, before using in parallel or series, it is recommended to evaluate the system’s tolerance to indicators such as ripple, current distribution, and transient response to ensure long-term stable operation.
