Versatile Industrial Power Supply Takes High Voltage Input
and Yields from Eight 1A to Two 4A Outputs вЂ“ Design Note 520
Martin Merchant
Introduction
TodayвЂ™s industrial electronic systems contain many
of the same components as consumer electronicsвЂ”
microcontrollers, FPGAs, system-on-chip ASICs and
other electronicsвЂ”requiring multiple low voltage rails
at widely varied load currents. Industrial applications
can also demand a pushbutton interface, an alwayson supply for a real-time clock (RTC) or memory and
the ability to take input power from a high voltage
supply. Other required features may be a watchdog
timer (WDT), a kill or reset button, software adjustable
voltage levels and error reporting of low input/output
voltages and high die temperature.
The LTC В®3375 is a highly configurable multioutput
step-down power converter that offers the features
often required by industrial electronics while providing the flexibility to configure various outputs with
maximum currents ranging from 1A to 4A.
Configurable Maximum Output Current
The LTC3375вЂ™s eight 1A channels can be combined to
produce various combinations of 1A, 2A, 3A and 4A
buck regulators, as shown by the 15 different output …
