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 resistance, it is possible to use it according to various output conditions. Features 1. Input Operating Voltage Range 3.0V~5.5V 2. Shutdown Supply Current 0.1µA (Typ.) 3. Temperature Range −30~+85°C 4. DC/DC converters Output Voltage 1.0V~PVIN Accuracy ±2% Maximum Output Current 1.5A / 1ch Oscillator Frequency 2MHz (Typ.) Output Voltage is changeable in external parts. Built-in start/stop sequence circuit. Output OverVoltage Protection function 0.72V (Typ.) Built-in So...
