Description
The FAN21SV04 Tiny Buck™ is a highly efficient, small-footprint, programmable-frequency, 4A, integrated synchronous buck regulator. FAN21SV04 contains both synchronous MOSFETs and a controller/driver with optimized interconnects in one package, which enables designers to solve highcurrent requirements in a small area with minimal external ponents, thereby reducing cost. Onboard internal 5V regulator enables single-supply operation for input voltages >6.5V. The FAN21SV04 can be configured to drive multiple slave devices OR synchronize to an external system clock. In slave mode, FAN21SV04 may be set up to be free-running in the absence of a master clock signal....
