PMIC AC/DC converters and offline switchers are components used in a wide range of applications, such as embedded and commercial systems, where they generate and regulate voltages and currents. The VIPER16HD is one of the most advanced PMIC AC/DC converters and offline switchers available and is ideal for those applications requiring high performance, accuracy, and reliability.

Application Field

The VIPER16HD is a constant-voltage/constant-frequency solution that can be used in a wide range of applications. These include embedded systems, telecommunication systems, industrial and domestic control systems, lighting systems, computing systems, automotive, industrial and medical applications. Its small size, power density, accuracy and reliability make the VIPER16HD ideal for these applications. Its flexibility allows it to be used in different topologies such as boost, buck, flyback, and bridge converters.

Working Principle

In its most basic form, the VIPER16HD operates as a buck converter. A buck converter is a type of DC to DC converter that takes a higher input voltage and reduces it to a lower output voltage. The converter does this by turning a switch, usually a MOSFET, on and off to create a pulse-width modulated (PWM) output. The PWM output is filtered to provide a lower DC voltage. This is the most efficient and accurate way to produce a DC voltage from an AC voltage source.

The VIPER16HD also features a high-level operation mode. This mode allows the converter to work in a boost, flyback, or bridge topology. In the boost topology, the VIPER16HD adjusts the pulse-width modulation to increase the output voltage after being boosted by an external inductor. The flyback topology is the most efficient for ac/dc applications, as it allows the inductor to store energy when the switch is turned off. In the bridge topology, the PWM circuit has four switches (two in series and two parallel) to create a bridge rectifier. The bridge rectifier is then used as a DC output.

Finally, the VIPER16HD uses Pulse Frequency Modulation (PFM) for low-power applications. PFM reduces the switching losses in the converter and makes it more efficient. This makes it perfect for low-power applications, such as in battery-powered or portable devices.
