Product Overview

The ADM00812 from Microchip is a MIC7401 5 buck 1 boost evaluation board. It is developed to evaluate the capabilities of the MIC7401 power management integrated circuit (PMIC). The board features 5 DC-DC buck converters capable of delivering 3A each and a boost converter with a 200mA current capability and I2C programmable output voltages. The MIC7401 evaluation board also features the MCP2221 USB to I2C bridge that enables direct communication and programming functionality by connecting the MIC7401 to the Graphic User's Interface (GUI).​ The I2C on-the-fly EEPROM programmability features buck and boost output voltage scaling, power-on-reset threshold and delay, power-up sequencing/sequencing delay, buck and boost current limit, soft-start and global power-good masking, buck and boost pull-down when disabled, individual ON/OFF and standby modes.
  • Dual power mode: stand-by and normal mode, ultra-fast buck transient response
  • 2MHz boost switching frequency, 1.3MHz buck operation in continuous mode
  • 93% peak buck efficiency, 85% typical efficiency at 1mA, I2C interface up to 3.4MHz
  • Input voltage: 2.4V to 5.5V
  • Five independent synchronous bucks up to 3A
  • 200µA quiescent current (all regulators on)
  • MCP2221 USB to I2C bridge for easy GUI communication
  • 23µA/70µA buck/boost typical quiescent current
  • 1.5% output accuracy over temperature/line/load
  • Thermal-shutdown and current-limit protection​
