Dual 20A/Single 40A Step-Down Power Module
ISL8240M
The ISL8240M is a fully-encapsulated step-down switching
power supply that can deliver up to 100W output power from a
small 17mmx17mm PCB footprint. The two 20A outputs may
be used independently or combined to deliver a single output
of 40A. Designing a high-performance board-mounted power
supply has never been simpler -- only a few external
components are needed to create a very dense and reliable
power solution.
1.5% output voltage accuracy, differential remote voltage
sensing and fast transient response create a very
high-performance power system. Built-in output overvoltage,
overcurrent and over-temperature protection enhance system
reliability.
The ISL8240M is available in a thermally-enhanced QFN
package. Excellent efficiency and low thermal resistance
permit full power operation without heat sinks or fans. In
addition, the QFN package with external leads permits easy
probing and visual solder inspection.
