DESCRIPTION
Demonstration circuit DC2061 is a DC/DC synchronous
boost converter featuring the LTC®3784 constant
frequency current mode synchronous boost
controller. The DC2061A operates over a 6V to 60V
input, develops a 48V output and provides 3A to 12A
of output current as shown in Figure 3. The 150kHz
(2 • 150kHz at the output) constant frequency operation
results in a small and efficient circuit. The converter provides
high output voltage accuracy (typically ±3%) over
wide load range with no minimum load requirement. The
demonstration circuit can be easily modified to generate
different output voltages.
The DC2061 has a small circuit footprint. It is a high performance
and cost effective solution for telecom, automotive
and Power over Ethernet applications.
