PMIC (Power Management Integrated Circuit) technology offers different options and solutions that allow the movement of electrical power into, through and out of electronic circuits. One of the solutions, AC/DC converters, comprises AC/DC power supplies, battery chargers and DC/DC converters. Offline switch-mode power supplies designers use components such as the VIPER53SP13TR AC/DC converter.

VIPER53SP13TR Application field

The VIPER53SP13TR AC/DC converter is designed for the secondary rectification of isolated flyback or isolated forward isolated converters. The input voltage is 100 to 277 VAC and operating frequency is from 50Hz to 60Hz. With a maximum power limit of 40W and a maximum load current of 2A, the VIPER53SP13TR is designed to create a highly efficient dc/dc power solution. The VIPER53SP13TR is also used for other secondary power solutions such as constant voltage (CV) and constant current (CC) power consumption as well as powering solid state lighting devices.

VIPER53SP13TR Working Principle

The working principle behind the VIPER53SP13TR AC/DC converter is the transfer of electrical energy from one location to another using direct current (DC). DC power is the form of electrical power that cars, cell phones, and computers use to operate. The VIPER53SP13TR transfers the AC voltage from the source into a DC voltage that is suitable for the corresponding application. This conversion process is achieved through the use of semiconductor switches and storage elements such as capacitors.

At the rectifier stage, semiconductor components known as diodes act as one-way valves and allow current to pass through them only in one direction. This allows the alternating current to be rectified, creating a unidirectional line of current. This is then transformed through a high-frequency transformer into a low-voltage, high-current direct current.

The next stage is the regulation of the voltage and current. The voltage and current are regulated using switches connected to a DC voltage source. The voltage is then put through the primary switch, which acts as a transformer, converting it into a specific output voltage. The current is regulated with a sense resistor for output current control and limits its maximum value. Once regulated, the current and voltage can be used to operate the desired device or application.

The VIPER53SP13TR is a highly efficient AC/DC converter as power losses associated with the rectification of the AC voltage are minimized. The built-in protection circuitry that sets the power limits and self-protection limits, along with its wide operating voltage range, makes it a reliable and efficient choice for a variety of applications, from basic power supplies and chargers to complex industrial power conversion solutions.
