The SG3525AP013TR is a DC-to-DC switching controller integrated circuit (IC) that is part of the voltage regulator family of products. This IC is specifically designed to regulate voltage levels in multiple power systems or sub-systems. By utilizing the efficient and reliable switching architecture, it is able to provide a wide range of output voltages at the maximum current efficiency and minimize heat with Synchronous Rectification (SR).

The SG3525AP013TR feature a durable and high-efficiency full-bridge (H-type) architecture, allowing for temperature compensated switching current and voltage to be more accurate and reliable. The gate drivers are built-in, eliminating the need for an external driver. This makes the IC more space-efficient and suitable for multiple applications, ranging from personal computers to power supplies in industrial equipment.

As a voltage regulator, the SG3525AP013TR is capable of controlling output power to the load or loads it is connected to. To do this, the IC switches at a set frequency of up to 500kHz and is able to provide a wide range of outputs. Its maximum output current can vary up to 3.5A. The fixed, adjustable, or logic-level frequency control sets the switching frequency and can be used to provide over-current protection and access to external control signals. The SG3525AP013TR also includes current-mode control, top-off constant frequency, and a low-battery turn-on schematic that guarantees a safe and reliable operation.

The SG3525AP013TR is able to provide adjustable output voltage for use in applications like switch mode power supplies, dc-dc battery chargers, dc-dc converters, and voltage conversion. It also features an on/off control pin and enable/disable function that allows for a user to enable or disable outputs as needed. These features make the SG3525AP013TR suitable for a variety of applications, from on/off control of relay systems to field output power control.

In addition to its wide array of features and benefits, the SG3525AP013TR is designed to be highly efficient. This is done by utilizing SR to minimize heat generated by the switching action of the IC. SR provides a higher current efficiency by reducing the power losses typically found in schottky diodes and improving system thermal performance.

Another feature of the SG3525AP013TR is its built-in current overload protection. This feature is triggered when the current exceeds a predetermined level. The overload protection helps to protect the IC from damage due to excessive current. The addition of a built-in reverse current protection further enhances the safety of the IC.

Overall, the SG3525AP013TR is a versatile and reliable DC-to-DC switching controller IC that is able to provide a wide range of output voltages, while providing efficient and reliable switching. With a wide range of features and benefits, the SG3525AP013TR is suitable for a wide range of applications, ranging from personal computers to industrial equipment.
