The MIC7400 and MIC7401 are available in a small 4.5 x 4.5mm FQFN package. They combine five independent 3A synchronous buck converters, an independent 200mA non-synchronous boost converter, and programmable features. They are targeted at SSDs and applications deploying processors and SoCs, including smart-home and IoT (Internet of Things) devices.

The devices are configurable via an I²C interface and an internal EEPROM. They offer dynamic output voltage scaling, normal and standby modes, and start-up power sequencing order and delays. Using only 200mA of quiescent current in normal mode, they have a low power standby mode to reduce the quiescent current by decreasing output voltage or turning off any individual output.

Configuration and monitoring is via a GUI tool. Both PMICs operate from a 2.4 to 5.5V input and can provide an output of 0.8 to 3.3V for the buck regulators with 1.5% output accuracy over line, load and temperature. The integrated boost regulator is capable of regulating output voltages from 7 to 14V. Other configurable features include soft-start rise/fall times, current limit, output active discharge in-addition to the threshold and delay for the integrated power-on-reset circuitry. Operating temperature range is -40 to 125°C.
