The RD278 reference design provides up to 95 percent efficiency depending on the input and output conditions and operates over a wide input voltage range from 8V to 20V. FAN21SV06 can be configured to operate in either master or slave mode. In slave mode, the regulator accepts external synchronizing signals and synchronizes the output switching frequency with the input signal. The output voltage, switching frequency and current limit functions on this design can be reconfigured to suit the application by changing few components.
The FAN21SV06 integrates a controller, driver and optimized power MOSFETs in a compact 5mm x 6mm MLP package. This device has a wide operating range of 6.5V to 24V, and is ideally suited to generate various system level voltage rails easily. An added advantage of the FAN21SV06 is that the regulator can be enabled separately allowing power-sequencing in point of load (POL) applications.
Fairchild offers a wide range of reference designs that reduce board space, simplify design, ensure system reliability and speed time to market. These production-ready designs are important in enabling OEMs to shorten their design time and bring their applications to market faster.
