SAN JOSE, USA: Design and system engineers of consumer, industrial and medical electronics employing low dropout regulators (LDO) have sacrificed DC-DC regulator efficiency, which adversely affects the overall efficiency of the design, in order to take advantage of an LDO’s ease-of-use.
Fairchild Semiconductor’s new power DC-DC micro-module offers customers the ability to reduce board space, reduce component count and improve the overall system efficiency of their designs. Alternative efficiency improvement methods include implementing a traditional DC-DC switching converter, which requires in-house design capability and delays time-to-market.
The FAN4603 micro-module DC-DC buck solution, unlike a traditional switching DC-DC implementation, integrates the passive components and the DC-DC regulator into a single ‘solder-and-play’ module. As a complete package, this micro-module is a highly integrated, robust DC-DC solution, reducing component count by at least three components.
This device also allows designers to use an advanced, high-frequency DC-DC solution in their end applications, taking advantage of higher efficiency, robust DC-DC power, reducing the footprint by 40 percent and simplifying layout and applications validation testing, without lengthening design times and qualification cycles, and shortening overall time-to-market.
The FAN4603’s proprietary architecture consumes very low quiescent current and delivers ultra-fast transient response. With quiescent current of 35µA typ. in standby mode, this solution is able to provide best-in-class transient response, making it more reactive to fast changes in load requirements.
The FAN4603 is housed in a 4mm x 2.5mm MLP package.
