FEB278-001 TinyBuck™ Integrated Synchronous Buck Evaluation Board

The FAN210SV06 TinyBuck™ is a highly efficient, small-footprint, programmable-frequency, 6A integrated synchronous buck regulator. FAN21SV06 contains both synchronous MOSFETs and a controller/driver with optimized interconnects in one package, which enables designers to solve high-current requirements in a small area with minimal external components, thereby saving cost. On-board internal 5V regulator enables single-supply operation for input voltages >6.5V.

The FAN21SV06 can be configured to drive multiple slave devices OR synchronize to an external system clock. In slave mode, FAN21SV06 may be set up to be free-running in the absence of a master clock signal.

External compensation, programmable switching frequency, and current-limit features allow for design optimization and flexibility. High-frequency operation allows for all ceramic solutions.

Fairchild’s advanced BiCMOS power process combined with low-RDS(ON) internal MOSFETs and a thermally efficient MLP package provide the ability to dissipate high power in a small package. Integration helps to minimize critical inductances making layout simpler and more efficient compared to discrete solutions.

Output over-voltage, under-voltage, over-current and thermal-shutdown protections help protect the device from damage during fault conditions. FAN21SV06 prevents pre-biased output discharge during startup in point-of-load applications.
