DC to DC converters are essential components in many electrical and electronic systems, allowing for efficient power transfer between different voltage sources. The FS20-12 is one such converter, designed to provide step-down conversion and power regulation for DC sources. This article will provide an overview of the FS20-12 application field and working principle.

The FS20-12 is specifically designed for use in industrial applications such as motor drives, motor controller circuitry, robotics and machine control. It is also utilized in automotive applications, including power management, battery charging and power conditioning. It is rated for up to 20 amperes, making it suitable for medium- to high-current applications in environments subjected to extreme temperatures or where efficient power conversion is critical.

The converter can accept input voltage of up to 60 volts DC and output voltage of up to 12 volts DC. It is capable of providing isolation between the input and output lines, allowing for improved safety and reliability. It features advanced protection circuitry, including thermal overload protection, short-circuit protection, under-voltage lockout and over-current protection, making it highly reliable even in harsh operating conditions.

The FS20-12 operates in two distinct modes: linear current-mode control and pulse-frequency modulation (PFM). In linear current-mode control, the converter’s output voltage is regulated by a linear feedback loop that maintains a fixed voltage over a wide input voltage range. In PFM mode, the output voltage is controlled by a pulse-width modulation (PWM) signal that regulates the cycles of the output switch. The converter can switch between the two modes depending on the load conditions.

The FS20-12 is a high-efficiency, high-reliability DC to DC converter, ideal for use in medium- to high-power applications. It offers efficient power transfer, advanced protection circuitry, and two distinct control modes, allowing for flexible and reliable operation even in harsh industrial environments. With its input voltage range of up to 60 volts, it is highly suitable for environment characterized by extreme temperatures or high-current applications.
