LTC3568
1.8A, 4MHz, Synchronous
Step-Down DC/DC Converter
Features Description n n n n The LTC®3568 is a constant frequency, synchronous
step-down DC/DC converter. Intended for medium power
applications, it operates from a 2.5V to 5.5V input voltage
range and has a user configurable operating frequency
up to 4MHz, allowing the use of tiny, low cost capacitors
and inductors 2mm or less in height. The output voltage
is adjustable from 0.8V to 5V. Internal sychronous 0.11Ω
power switches with 2.4A peak current ratings provide
high efficiency. The LTC3568’s current mode architecture
and external compensation allow the transient response
to be optimized over a wide range of loads and output
capacitors. n n n n n n Uses Tiny Capacitors and Inductor
