The first two members of the family, the 20A, AOZ2367QI and the 25A, AOZ2368QI, have been introduced. The compact, efficient power converters target next-generation chipsets used in high-end TVs, servers, data storage systems, networking and other compact PC systems.

These microprocessors and SoCs require more power to do fast calculations as well as to provide more add-on functions. Implementing much higher output power in a DC/DC converter however, often requires several external components such as high current and low turn-on resistance MOSFETs. Design of such converters is simplified by integrating the company’s advanced MOSFET technology to power, and its packaging to provide better thermal management capabilities to ensure a stable and robust environment.

According to the company, its MOSFETs enable high efficiency over the entire load range with low on resistance (one to 4mΩ, and light-load efficiency that is further boosted with an optional pulse frequency mode (PFM).

The 20A and 25A devices are available in a footprint-compatible QFN 5.0 x 5.0mm package allowing designers an easy upgrade path as power requirements increase.

The regulators operate over a wide input voltage range of 4.5 to 24V with output voltages adjustable down to 0.6V. The proprietary COT architecture provides fast load transient response performance and allows a stable and low voltage ripple operation with small ceramic capacitors, says the company, adding that competing solutions require several external components when using all-ceramic capacitors and need to generate a larger output ripple voltage to stabilise the circuit.  The input feed forward feature provides a constant switching frequency over the entire input voltage range to alleviate noise concerns.

The AOZ2367QI and AOZ2368QI are immediately available in production quantities with a lead-time of 12 weeks.
