This is a 5V 700mA 3.5W AC-DC Step Down Module. This Power Supply Module designed as an ultra- thin and compact device with a supply voltage of 220V AC. It is an isolated switching step-down power supply module with an output voltage of 5V DC from 220V AC. It offers a power rating of 3.5 Watt makes it ideal for small projects that need a 5 volt supply from mains. This power supply module particularly replaces lots of parts from the traditional power supply like diodes, voltage regulators, and transformers.
This Power Supply Module offers numerous advantages such as low-temperature rise, low power, high efficiency, high reliability, high-security isolation, etc. Since it is a buck convertor the output voltage will be always lower than the input voltage. It is an easy-to-use, nonsynchronous, step-down AC-DC converter with a wide input voltage range of for the HV version. It is capable of driving a load up to 700mA with high efficiency.
This step-down provides excellent line and load regulation. This module includes internal frequency compensation and a fixed-frequency oscillator. As a result, minimize external components and simplify power supply design. It provides a switch-mode power supply function with high efficiency compared to the popular three-terminal linear regulators, especially with higher input voltages. This module works with Freeduino UNO, other mainboards, and basic modules. Moreover, this module features thermal shutdown, current limit protection and makes it suitable for wide range of applications.
