The STR-A6062HD is an application-specific integrated circuit (ASIC) designed to convert alternating current (AC) to direct current (DC) for use in both commercial and consumer electronic applications. The STR-A6062HD is part of a family of ASICs designed for use in offline switchers, which are used in a wide range of applications from LCD and LED displays to power supplies and voltage conversion. The STR-A6062HD is a highly integrated, AC/DC switching converter with active factor correction, constant-voltage/constant-current control, and full protection features.

The STR-A6062HD belongs to a family of second generation offline switchers which builds on the success of previous generations by improving energy efficiency and performance. The ASIC is manufactured using a high-voltage BCDMOS process, and includes features such as a precision low-dropout regulator that improves output ripple, a low-impedance power stage, a programmable oscillator and Independent Gate Drive, and a high-efficiency power factor correction circuit. The ASIC also features numerous protection features such as Under Voltage Lockout, Over Current Protection, Over Temperature Protection, and Soft Start.

The STR-A6062HD is designed to operate in a wide range of applications from 9W down to 1W military and space applications, including small form factor applications. The ASIC can be configured for input voltages of 3.3V to 400V AC, and output voltages from 1.6V to 450V. This flexibility allows the STR-A6062HD to be used in both flyback and forward designs, and produces highly regulated DC outputs with high output accuracy and low ripple and noise.

The key to the STR-A6062HD\'s efficient operation is its circuit design. The Reactive Energy Compensated Flyback Converter (RECFB) architecture integrates Active Factor Correction (AFC), constant-voltage/constant-current control, and full protection features into a single chip design. The RECFB architecture reduces the number of components in the power stage, resulting in reduced system cost and improved energy efficiency, while the AFS circuit works to reduce noise, reduce input ripple and improve overall efficiency. The patented independant gate drive allows for driving wide range of MOSFETS for both synchronous and non-synchronous applications.

The STR-A6062HD is an ideal solution for a wide range of applications, including industrial and automotive applications, LCD monitors, ac/dc adapters, and medical equipment. The ASIC is designed to meet the requirements of the latest safety standards, including RoHS and CE marking, and is backed by a three year quality and reliability guarantee. The STR-A6062HD is easily configurable, with design software available through the STR website, as well as through strategic partner and partner sites.
