The FAN21SV04 TinyBuck? is a highly efficient,
small-footprint, programmable-frequency, 4 A,
integrated synchronous buck regulator.
FAN21SV04 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 reducing cost. On-
board internal 5 V regulator enables single-supply
operation for input voltages >6.5 V.
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.
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-R DS(ON) internal MOSFETs and a
thermally efficient MLP package, provide the ability
to dissipate high power in a small package.
Integration helps minimize critical inductances,
making layout simpler and more efficient compared
to discrete solutions.
Output over-voltage, under-voltage, over-current, and
Applications
thermal-shutdown protections help protect the device
from damage during fault conditions. FAN21SV04
