For stable regulation, ensure the input voltage is at least 1.5V1.5 cap V higher than the desired output. Heat Dissipation: If drawing more than
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:
Acting as a highly decentralized point-of-load (POL) regulator on custom motherboard environments.
22 mm x 17 mm x 4 mm (or 25 mm x 20 mm x 4 mm depending on board trim) Module Pinout Configuration Hw-133-v1.0 Datasheet
The HW-133-v1.0 is almost universally a . It is functionally identical to the more commonly known FC-37 or YL-83.
The Hw-133-v1.0 includes a small blue potentiometer marked "103" (10kΩ). Turning it adjusts the trip point for the digital output.
The core performance of the HW-133-V1.0 module is dictated by the underlying MP1584EN IC datasheet. It utilizes synchronous rectification to maintain high conversion efficiency even under heavy loads. Specification Notes / Conditions 4.5V to 28V DC Input must be higher than output Output Voltage Range 0.8V to 20V DC Adjustable via onboard potentiometer Maximum Output Current 3.0 Amperes Peak current rating Continuous Operating Current 1.5 Amperes Recommended without external cooling Maximum Conversion Efficiency Varies based on VINcap V sub cap I cap N end-sub VOUTcap V sub cap O cap U cap T end-sub differential Switching Frequency 1.0 MHz (Typical) to 1.5 MHz (Max) High-frequency reduces ripple Output Ripple Measured at no-load state Quiescent Current Standby mode power draw Operating Temperature -40°C to +85°C Industrial grade operational range Physical Dimensions 22 mm × 17 mm × 4 mm Ultra-small PCB layout footprint Pinout Configuration For stable regulation, ensure the input voltage is
