Application specific regulators target Intel’s Tiger Lake
Alpha and Omega Semiconductor (AOS) has launched a family of application-specific EZBuck regulators aimed at Intel’s Tiger Lake processor platform.
The 16A AOZ2264VQI and 30A AOZ2369VQI are offered in QFN 4 x 4 and QFN 5 x 5 package with optimised thermal management to support the auxiliary voltage rails (VCCIN_AUX) in notebook and desktop computing systems.
Intel’s Tiger Lake platform consists of two rails. One rail powers the core and graphics processors while the VCCIN_AUX powers the auxiliary processor. This processor supports add-on features in personal computing systems such as audio, video, connectivity, and other functions that enhance user experience. Feature-rich personal computing systems require a VCC_AUX rail with high currents.
The 2-bit voltage ID (VID) pins allow the VCCIN_AUX power rail to adjust with voltage for 0V, 1.1V, 1.65V, and 1.8V depending on multiple systems operating modes from a wide input voltage range from 4V to 28V.
Both devices have also passed all the validation requirements included in the Intel Tiger Lake Platform Component List (PCL). This test puts the regulator through stringent tests to ensure compliance with Intel specifications. AOS’s proprietary NFET-based COT architecture provides fast load transient response performance and enables stable and low voltage ripple operation with small-sized ceramic capacitors, further reducing the footprint.
“The two current capabilities offered by the AOZ2264VQI and the AOZ2369VQI offer designers a scalable solution to support Intel Tiger Lake’s multiple platform SKUs such as UP3, UP4, and H-Line. In state-of-the-art laptops, the system board has shrunk considerably to make way for system fans for thermal management or larger batteries to improve battery life. Form factors for personal computers are always shrinking. Utilizing AOS’s EZBuck regulator platform technology enables AOS to solve the system designer’s problem of ever-shrinking PCB real estate,” said Wayne Lee, Power IC Marketing at AOS.
The AOZ2264VQI is immediately available in production quantities with a lead-time of 12 weeks. The unit price for 1,000 pieces is $1.129 for the AOZ2264VQI and $1.69 for the AOZ2369VQI.
