Fairchild Semiconductor has developed the FAN5362, a 3MHz 500mA synchronous Buck regulator, using a proprietary architecture with synchronous rectification, to meet the increasing demand for memory storage and to power larger SD flash memory cards.

According to Fairchild, the device is ideal for cell phone designers who need to support high capacity SD flash memory cards. In addition, FAN5362 provides high efficiency and optimised control designed specifically for low headroom operation.

The company claims that the FAN5362 works in conjunction with small input/output capacitors and 0805 multi-layer chip inductors. Compatibility with these passive components allows system designers to pick chip inductors and capacitors that consume less board space at a lower cost, resulting in smaller and more affordable end applications.

Further, the DC/DC converter is packaged in a 0.96 X 1.31mm WL-CSP package with a sleek, low profile of 0.6mm, conserving board space for these space-constrained applications.

The FAN5362 is also available in other fixed output voltage options ranging from 1.8 – 3.6V. This easy-to-design offering supports the quick design cycles found in the mobile device market, making it an ideal choice for cell phones, tablets, eBooks, PMPs, DSCs, GPS and lithium-ion portables.
