ISL8240M開發(fā)板套件編程器的評(píng)估板-DC/DC與AC/DC（離線）SMPS規(guī)格書PDF中文資料

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.
