Hi everyone,
: Some users have reported that input voltages above 24V (despite the 28V rating) can cause instability or failure if the output is under heavy load. Trimpot Adjustments Hw-133-v1.0 Datasheet
The is a popular adjustable buck (step-down) DC-DC converter module, often featuring the LM2596 voltage regulator. It is widely used in DIY electronics to convert higher DC voltages down to stable, lower levels (e.g., dropping 12V or 24V down to 5V or 3.3V). Technical Summary & Field Performance Hi everyone, : Some users have reported that
high-efficiency switching regulator, making it ideal for applications requiring a small footprint and low heat dissipation, such as RC aircraft, DIY electronics, and portable power solutions. Technical Specifications Value / Range Input Voltage 4.5V to 28V DC Output Voltage 0.8V to 20V DC (Adjustable via Trimpot) Output Current 3A Maximum Switching Frequency 1.0 MHz (Typical) up to 1.5 MHz Efficiency Operating Temperature -45°C to +85°C Dimensions 22mm x 17mm x 4mm Output Ripple Key Features High Power Density : Its compact size ( ) allows it to fit into extremely tight spaces. Precision Adjustment : Hw-133-v1
These values are practical defaults used in application design; confirm against your unit’s silkscreen or vendor sheet where available.
