Regulator IC with the Soft-Start MM192x Series
Regulator IC with the Soft-Start
Monolithic IC MM192x Series
Outline
This IC is 1A regulator IC with soft-start. When Cs pin is connected with a capacitor, the output voltage is
started up slowly. This IC can reduce a rush current by the soft-start.
Therefore a transformer in a power supply for this IC can be small, and it is possible to reduce a total cost in
the power supply system. And this IC can be turned off by Cont pin.
Package TO-252-5 or HSOP-8 were used for this device.
