Device Overview

Summary

The MIC33M350 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 at light loads, while still having ultra-fast transient response.

The MIC33M350 output voltage is set by two VSEL (Voltage Selection) pins, up to nine different values. This method eliminates the need for an external feedback resistor divider and improves the output voltage setting accuracy. 

The 2.4V to 5.5V input voltage range, low shutdown and quiescent currents make the MIC33M350 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 MIC33M350 pinout is compatible with the MIC33M356 I2C-based programmable regulator version, such that applications can be easily converted. An open-drain Power Good output is provided to indicate when the output voltage is within 9% of regulation and facilitates the interface with an MCU, or power sequencing. If set in shutdown (EN=GND), the MIC33M350 typically draws 1.5 µA, while the output is discharged through 10 ohm pull-down.

The MIC33M350 is available in a thermally efficient, 24 Lead 3mm x 4.5mm x 1.8mm thin QFN package, with an operating junction temperature range from –40°C to +125°C.
