DESCRIPTION
LTC7880
High Voltage Dual Step-up DC/DC Converter
with Digital Power System Management
Demonstration circuit 2728A is a high voltage, dual output
boost converter with 12V to 24V input range. The output
voltage is adjustable from V
IN
to 48V. Each output can
supply 5A maximum load current. The demo board has a
controller, which is a 60V dual output step-up
controller with digital power system management. Please
see LTC7880 data sheet for more detailed information.
DC2728A powers up to default settings and produces
power based on configuration resistors or its nonvola-
tile memory (NVM) without the need for any serial bus
communication. This allows easy evaluation of the DC/
DC converter. To fully explore the extensive power sys-
tem management features of the part, download the GUI
