Description
The FAN210SV06 TinyBuckTM 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.
