The SMT12F series is a new range of ultra-compact non-isolated
point-of-load converters for space-critical applications. The new
SMT12F Typhoon™ family surface-mount converter has a foot-
print of just 13.5 x 16 mm - and unlike competitive products on
the market, requires only the addition of a small number of
ceramic output capacitors to realise a complete high-performance
point-of-load (POL) solution. The SMT12F is primarily intended for
use on very densely packed, high functionality boards and for
powering advanced silicon including network and communication
processors, DSPs, FPGAs and ASICs. A key advantage of the
SMT12F is that it only needs the addition of five 22 μF ceramic
output capacitors to provide a complete full-specification, high
efficiency POL solution with transient response capabilities that
extend up to 300 A/μs. The total board space required for the
module and capacitors is a mere 300 mm2, facilitating easy
co-location with the load.
