ADM00812

ADM00812 is a MIC7401 5 BUCK 1 BOOST PROGR REG evaluation board. MIC7401 evaluation board was 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 board also features test points for monitoring each channel's output voltage, input voltage test points, different functionality connectors and high power turret connectors for both input and output voltages.

• Input voltage range from 2.4V to 5.5V
• 200μA quiescent current (all regulators on), 93% peak buck efficiency, 85% typ efficiency at 1mA
• Dual power mode: stand-by and normal mode, I2C interface up to 3.4MHz
• MCP2221 USB to I2C bridge for easy GUI communication
• I2C on-the-fly EEPROM programmability, featuring buck and boost output voltage scaling
• Power-on-reset threshold and delay, power-up sequencing/sequencing delay
• Buck and boost current limit, buck and boost pull-down when disabled
• Individual ON, OFF, and standby modes, soft-start and global power-good masking
• 2MHz boost switching frequency, 1.3MHz buck operation in continuous mode
• Ultra-fast buck transient response and thermal-shutdown and current-limit protection
