PMIC - AC DC Converters, Offline Switchers

AC-DC converters, sometimes referred to as offline switchers, are power electronic devices that convert alternating current (AC) to direct current (DC). AC-DC converters can be found in a variety of consumer and industrial applications, including consumer electronics (e.g., battery chargers, power supplies, etc.), telecommunications, automotive, and industrial applications. top267eg is one such AC-DC converter.

TOP267EG is a high-voltage, high-efficiency, monolithic, AC-DC converter designed to convert single-stage input voltage of up to 264V AC/DC to 12V-24V output voltage. It is suitable for universal AC line input, wide input range applications, and features a built-in active PFC (power factor correction) circuit. Thanks to its low profile, compact size, and high efficiency, it is ideal for fluorescent lighting, function power supplies, as well as other similar systems.

TOP267EG utilizes a patented integrated topology that reduces the number of external components and cost. The internal circuitry incorporates a control IC and control logic, which regulates the internal sensing block and the active PFC. To minimize input current ripple, the maximum voltage range of the TOP267EG is boosted for improved power factor correction. In addition, the internal MOSFETs used in the power train are integrated for reduced system costs and improved reliability.

The TOP267EG is designed to convert AC/DC input voltage of up to 264V to 12V to 24V output voltage. The TOP267EG utilizes a unique control method that helps to reduce switch-on current at low line, to further improve power factor and efficiency over the entire input voltage range. In addition, the TOP267EG features an integrated PFC controller with 0.8 power factor target, and an over 10A output current. It also includes a unique thermal compensation feature that helps to ensure optimal efficiency throughout the operating temperature range.

Additionally, it includes a variety of features to protect the system, such as overvoltage, overcurrent and overtemperature protection. The TOP267EG also features an active currentsense circuit, thermal compensation loop and an integrated MOSFET to reduce the size and internal voltage drops. Finally, the power device is designed for full-range input voltage, including 265V AC and is suitable for universal AC line input

In summary, the TOP267EG is a high-efficiency, high-voltage, monolithic AC-DC converter designed to convert single-stage input voltage of up to 264V AC/DC to 12V-24V output voltage. It is suitable for universal AC line input, wide input range applications, and features a built-in active PFC (power factor correction) circuit. In addition, it features a variety of features to protect the system, such as overvoltage, overcurrent and overtemperature protection. Thanks to its low profile, compact size, and high efficiency, the TOP267EG is ideal for fluorescent lighting, function power supplies, as well as other similar systems.
