描述 Description

The MIC33M356 is a high-efficiency, low-voltage input, 3A Continuous current synchronous step-down Power Module. The Constant-ON-Time (COT)control architecture with HyperLight Load? provides very high efficiency atlight loads, while still having ultra-fast transient response.The I2C interface allows programming the output voltagebetween 0.6V and 1.28V, with 5 mV resolution (-HAYMP and -FAYMP) or between 0.6V and 3.84V, with 10mV and 20 mV resolution (-SAYMP). Two different default voltage options (0.9Vand 1.0V) are provided so that the application can be started with a safevoltage level and then moved to high performance modes under I2Ccontrol. An open-drain Power Good output facilitates outputvoltage monitoring and sequencing. If set in shutdown (EN = GND), the MIC33M356 typically draws 1.5 μA, while the output is discharged through 10 ohm pull-down (if the outputdischarge feature is enabled). The MIC33M356 pinout is compatible with the MIC33M350, sothat applications can be easily converted.The 2.4V to 5.5V input voltage range, low shutdown andquiescent currents make the MIC33M356 ideal for single-cell Li-Ionbattery-powered applications. The 100% duty cycle capability provides lowdropout operation, extending operating range in portable systems. The MIC33M356 is available in a thermally efficient, 24-Lead 3 mm x 4.5 mm x 1.8 mm QFN package, with an operatingjunction temperature range from -40°C to +125°C
