AC/DC converters are the ultimate solution for efficient power conversion. The PM-15-12 is an optimized AC/DC converter that is specifically designed to deliver a combination of the highest possible efficiency and power density levels. It is a switching regulator with current-mode control, making it suitable for nominal outputs from 12W up to 20W. Its advanced technology and wide input voltage range enables it to be used in a variety of applications, such as automotive, telecom, industrial, medical, and consumer electronics.

Application Field
PM-15-12 is used in automotive, industrial, telecom, and consumer industries to convert low DC voltage into higher DC voltage. It is often used when a high power density with improved efficiency is required, such as for driving high-power LEDs or providing comprehensive power optimization for advanced aDDC and other digital systems.

Working Principle
PM-15-12 preserves the same basic topology of traditional buck converters, with the addition of unique features for improved system performance. As an AC/DC converter, it is designed to receive incoming AC voltage from the power grid, convert it to DC voltage, and then output it to the desired equipment or devices. The conversion process is achieved by a three-step converter circuit composed of two main parts: an input section and an output section. The input section consists of an input capacitor, resistor, diode, and inductor. The output section contains an output coil, power transistor, and Schottky rectifier.

The PM-15-12 uses an active current-mode control technique known as CCM Control. This technique provides superior control over the converter\'s input and output voltages over varying loads and temperatures. The regulator stage also leverages an adaptive on-time control algorithm to control the duration of both the voltage switching and current conduction phases. This improves the system\'s overall efficiency and reduces EMI noise. Additionally, the switcher works with protected feedback transfer function (FTF), allowing for simple loop stability and dynamic response control.

PM-15-12 is a high efficiency and high power density AC/DC converter specially designed to deliver peak performance and reliability. Its optimized and advanced features make it the ideal solution for critical power optimization applications, where both system power and heat dissipation levels are of paramount importance.
