ADM00829

The ADM00829 from Microchip is a MIC23158/9 3MHz dual 2A buck evaluation board. The MIC23158/9 evaluation board has been developed to evaluate the capabilities of the MIC23158/9 family of devices. The board is populated with the MIC23159 device and it’s set for the 1.8V(regulator 1), 1.5V(regulator 2) voltages. The evaluation board can be easily modified by interchanging the MIC23159 device with MIC23158.​ The MIC23158/9 evaluation board features independent enable connectors with individual pull-up resistors. To check the status of each regulator, power-good connectors are available for each regulator. The board can be powered from two independent voltage sources or a 0 ohm resistor can be placed on R3 so that both converters be powered from the same voltage source.

• Input voltage range from 2.7V to 5.5V
• Adjustable output voltage down to 1V, two independent 2A outputs
• Up to 94% peak efficiency
• 83% typical efficiency at 1mA
• Two independent power good indicators, independent programmable soft start
• 45μA typical quiescent current
• 3MHz PWM operation in continuous conduction mode
• Ultra-fast transient response, output pre-bias safe
• 0.1μA shutdown current
• Thermal shutdown and current limit protection, internal 225ohm pull-down circuit on output​
