Description
The Y5117 is a series of highly efficient point-of-load DC/DC power converters in a unique SIP style surface mount
package, designed to deliver low voltages at high currents in close proximity to loads. Extra-wide input voltage
range, programmable output voltage, and fast transient response are just a few of the integrated features that
minimize power system cost and time to market.
