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
footprint 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
mm

, facilitating easy co-location with the load.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated.
