Overview

The MIC33M356 is a I²C programmable, high-efficiency, low-voltage input, 3A current, synchronous step-down regulator power module with integrated inductor. The Constant On-Time (COT) control architecture with HyperLight Load mode provides very high efficiency at light loads, while still having ultra-fast transient response. The I²C interface allows programming the output voltage between 0.6V and 1.28V, with 5 mV resolution or between 0.6V and 3.84V, with 10 mV and 20 mV resolution. Two different default voltage options (0.9V and 1.0V) are provided so that the application can be started with a safe voltage level and then moved to high-performance modes under I²C control. An open-drain Power Good output facilitates output voltage monitoring and sequencing. If set in shutdown (EN = GND), the MIC33M356 typically draws 1.5 μA of current, while the output is discharged through a 10Ω pull-down resistor (if the output discharge feature is enabled). The MIC33M356 pinout is compatible with the MIC33M350, so that applications can be easily converted. The 2.4V to 5.5V input voltage range, low shutdown and quiescent currents make the MIC33M356 ideal for single-cell Li-Ion battery-powered applications. The 100% duty cycle capability provides low dropout operation, extending operating range in portable systems. The MIC33M356 is available in a thermally-efficient, 24-lead, 3.0 mm × 4.5 mm × 1.8 mm QFN package, with an operating junction temperature range of -40°C to +125°C.
