Hw-133-v1.0 Datasheet __full__ 【360p】

): Operating continuously near its maximum capacity yields internal power dissipation above

: Stepping down power for Arduino, ESP32, or Raspberry Pi systems.

Common ground reference point for the input power supply.

As a step-down (buck) converter, the input voltage must always be higher than the target output voltage (e.g., a 12V input is recommended for a stable 5V output). Summary Table: HW-133-v1.0 vs. LM2596

Are you integrating this inside an or an open environment? Hw-133-v1.0 Datasheet

Let me know which of the above you need, and I’ll get the right information to you right away!

The HW-133-V1.0 derives its excellent power density from its high-frequency buck topology. The board layout consists of five primary hardware zones:

The Hw-133-v1.0 typically separates into two boards: the (exposed copper tracks) and the control board (LM393). The control board has a 4-pin male header.

Never adjust the trimmer potentiometer while the module is under a heavy load. Always tune the target voltage using a multimeter on an open circuit first, lock the position, and then connect your target system. ): Operating continuously near its maximum capacity yields

When migrating from HW-133 adapters to modern solutions, consider:

Engineering communities continue to provide support for legacy Xilinx products through:

The datasheet touts the capabilities of the HW-133 module, and here is how they hold up in reality:

continuously, it is recommended to add a small heatsink or ensure active airflow. Summary Table: HW-133-v1
