The PSE-850-12 is an AC/DC converters which combines a high efficiency half bridge and full bridge DC/DC converter and a power factor corrected switch mode ac/dc converter for operation from a single-phase ac input source such as an ac mains or dc input. It provides a regulated dc output, which can be used to power dc loads, such as computers, devices, and automation systems.

The PSE-850-12 uses a low voltage, high-efficiency step-up dc/dc converter. It operates from an input voltage range of 24 Vdc to 48 Vdc and provides up to 12 A of output power. The output voltage is adjustable from 9 Vdc to 24 Vdc.

The PSE-850-12 converter has a wide range of potential applications in many fields. It can be used in industrial, automotive, medical, telecommunications, and consumer products. It is ideal for providing regulated power for high performance power supplies, such as DC/DC converters, switch mode power supplies, AC power adapters, and DC motor drives.

The PSE-850-12 is a single-channel multi-mode power converter that supports multiple output voltage and current levels. It has two operating modes: Pulse Width Modulation (PWM) and Phase Shifted Full Bridge (PSFB). The PSE-850-12 operates in either PWM or PSFB mode depending on the load current. In PWM mode, it uses an adjustable switching frequency to regulate output voltage by modulating the duty cycle of the output switching signal, while in PSFB mode, it employs fixed phase-shift to achieve the same output voltage control.

The PSE-850-12 is designed to maximize system efficiency with a wide range of input to output voltage ratios. It utilizes high and low-side MOSFETs to maximize efficiency over a wide input voltage range and can be programmed to overvoltage, overload, short-circuit, and overtemperature protection. The converter also incorporates current-mode control to reduce EMI and other spurious emissions from the switching power device.

In addition to providing better efficiency, the current-mode control also increases the dynamic response of the PSE-850-12 converter, which is particularly important in applications requiring a fast load response time. The converter also features a low-noise and low ripple output, making it suitable for sensitive load requirements. The PSE-850-12 is also resistant to line voltage flicker and is able to operate with line voltage variations up to 50%.

The PSE-850-12 provides a high-efficiency and cost-effective solution for applications requiring AC-DC power conversion. It is suitable for a wide range of applications such as PC power adapters, distributed power systems, and consumer electronics. The converter is highly reliable and designed to operate with minimal maintenance.
