MM3558, 2ch Synchronous Step-down DC/DC Converter + 1ch LDO + 2ch P-GOOD

MITSUMI 2ch Synchronous Step-down DC/DC Converter + 1ch LDO + 2ch P-GOOD MM3558 Series 2ch Synchronous Step-down DC/DC Converter + 1ch LDO + 2ch P-GOOD Monolithic IC MM3558 Series Outline This IC is a compound power supply IC which built in Synchronous Step-down DC/DC converter 2ch, LDO1ch, and P-GOOD2ch.

The ripple of the input current is decreased so that the DC/DC converter of 2ch may work by the opposite phase, and a low noise is achieved.

Because the output voltage can be set by external
