Hw-133-v1.0 Datasheet

Accepts unregulated positive DC voltage from your power source (

The HW-133 v1.0 is typically based on the high-frequency switching regulator, which allows for a miniature design without sacrificing power. Specification Input Voltage 4.5V to 28V DC Output Voltage 0.8V to 20V DC (Adjustable) Max Output Current 3A (requires heat sinking for sustained high loads) Switching Frequency 1.0 MHz (typical) to 1.5 MHz (max) Conversion Efficiency Operating Temp -40°C to +85°C Dimensions 25mm x 20mm x 4mm Key Features

The "brain" that handles the high-frequency switching. Hw-133-v1.0 Datasheet

The module integrates all the necessary auxiliary components, including the inductor, input/output filter capacitors, and a small trimmer potentiometer to adjust the output voltage. The board layout is optimized to include vias under the IC and inductor, which improve heat dissipation from these critical components.

Provides power distribution for Arduino, ESP32, STM32, and Raspberry Pi baseboards from standard industrial 12V/24V power supply units. Accepts unregulated positive DC voltage from your power

Interfacing 24V industrial control logic networks down to standard 3.3V or 5V logic processing environments.

Providing a steady voltage for high-power LED strips. The board layout is optimized to include vias

I can provide tailored layout patterns or recommend additional filtering capacitors to keep your electrical ripple minimal. Share public link

Provides a path for current when the internal switch is off.
