: By using high-frequency switching, this module minimizes energy loss as heat compared to linear regulators.
The "v1.0" simply indicates the PCB revision. If you have this board, you have a device designed to detect water, moisture, or rainfall. Hw-133-v1.0 Datasheet
The HW-133-V1.0 stands out due to its compact form factor and exceptional power density. Below is the verified engineering data for the module: Specification Notes / Conditions MPS MP1584EN High-frequency synchronous buck switcher Input Voltage Range 4.5V to 28V DC Must be higher than the target output Output Voltage Range 0.8V to 20V DC Fully adjustable via onboard potentiometer Maximum Output Current Peak rating; requires cooling for prolonged loads Continuous Output Current 1.5A to 2.0A Safe operation limit without active heatsinking Peak Efficiency Achieved at lower voltage differentials Switching Frequency 1.0 MHz to 1.5 MHz High frequency allows minimal ripple filter sizes Output Ripple Measured at standard 20 MHz bandwidth limit Quiescent Current Low standby consumption for battery use Operating Temperature -40°C to +85°C Industrial-grade thermal compliance range Physical Dimensions 22 mm x 17 mm x 4 mm Ultra-miniature footprint Pinout Configuration and Board Layout : By using high-frequency switching, this module minimizes
The HW-133-V1.0 leverages its 1.5 MHz switching frequency to minimize the size of its onboard filter inductor and ceramic smoothing capacitors. This design yields an exceptionally small layout suitable for weight-sensitive applications like RC aircraft and compact sensor enclosures. Setting the Output Voltage The HW-133-V1
