Dual Output Monolithic Supply with Integrated 3A Power
Switches and Operation to 2.5MHz in a 7mm Г— 4mm DFN
Mehdi Alimadadi There is no shortage of ICs to help designers build switching DC/DC switching power
supplies. Choices range from versatile controllers requiring a number of external
components, to fully integrated, monolithic solutions that benefit from a low external
parts count to minimize overall solution size. The LT8582 dual-channel converter offers
the versatility of a controller IC in a complete, monolithic dual-channel solution.
The LT8582 integrates two complete,
independent converters, including high
power 3A, 42V power switches. It can
operate up to 2.5MHz, and with its tiny
7mm Г— 4mm DFN package, fits into the
smallest spaces. It includes several features
that give designers the ability to optimize
the converter, such as soft-start, single-pin
feedback, single-resistor frequency setting,
master/slave power switches, separate
maximum commanded and fault current
limits, external PFET control for output
or input disconnect, FAULT protection,
PG pin for power supply sequencing, and
CLKOUT signal for out-of-phase synchronizing and die temperature monitoring.
FLEXIBILITY AND SIMPLICITY Each channel of the LT8582 can be …
