STR-A6063HD is a family of AC-DC and DC-DC converter ICs designed for cost-effective offline switching power supplies. It targets low power applications such as entry-level printers, game consoles and desktop computer systems. With the integrated functions and low external components, STR-A6063HD simplifies any design while allowing rationalization of part number. It is also ideal for applications such as home appliance and home theater.

The STR-A6063HD is a monolithic power IC consisting of: (1) a MOSFET, (2) a startup circuit, (3) pre-regulator, (4) VCC voltage regulator, (5) a PWM controller, (6) a Voltage sense amplifier and (7) output control circuit. The device serves an offline converter and switching regulator from rectified line AC voltage with Output voltage ranging from 8V to 65V.

The STR-A6063HD is a full featured, high efficiency AC-DC converter with a variety of features, making it suitable for a range of applications. It offers Primary-side feedback that help to build cost-effective and low EMI designs. The device also includes a precise 8V temperature compensated voltage reference to provide constant system operating voltage, as well as a low on/off threshold error. It is also capable of fast-transient response and low EMI.

As an offline AC-DC converter, the STR-A6063HD provides power conversion using either flyback or forward topologies, depending on the chosen application: the flyback model uses switching rectification to convert the AC input voltage into a DC output voltage. It also offers a wide range of output voltage settings, allowing the user to adjust the output voltage to their needs. This is especially useful in applications where the input voltage needs to be adjusted, such as LED lighting.

The STR-A6063HD also includes a power factor correction circuitry as part of its power system of converting rectified line AC voltage into DC output voltage. The power factor correction uses a capacitor (or series of capacitors) to absorb the high frequency components of the AC input waveform, thus reducing harmonics and interference, resulting in an improved power factor. This ensures that the overall output quality is improved and less power is lost in the conversion process.

In addition to its power conversion capabilities, the STR-A6063HD also offers protection against overload, overvoltage and short-circuit conditions. It also includes current limiting and thermal shutdown features to ensure safe operation of the chip. Furthermore, the PWM controller circuit can be modified for optimum system efficiency.

The STR-A6063HD is ideal for applications such as consumer electronics, home entertainment systems, industrial automation, LED lighting, and other applications requiring cost-effective, high efficiency AC-DC power solutions. With integrated features and low external components, the chip simplifies system designs while allowing rationalized part number. It is also capable of delivering stable and reliable power with low EMI and high efficiency.
