• Input Voltage Range: 6.0V to 24V
• Output Voltage Range: 0.9V to 5V set using external resistor divider
• 1.5% V
• Fixed Output Voltage Options 0.9V, 1.5V, 1.8V, 2.5V, 3.3V, 5V
• 2.0% V
• Integrated High-Side N-Channel Switch: 180 mΩ
• Integrated Low-Side N-Channel Switch: 120 mΩ
• 1A Output Current MCP16321
• 1 MHz Fixed Frequency
• Adjustable Output Voltage
• Low Device Shutdown Current
• Peak Current Mode Control
• Internal Compensation
• Stable with Ceramic Capacitors
• Internal Soft-Start
• Cycle by Cycle Peak Current Limit
• Under Voltage Lockout (UVLO): 5.75V (typical)
• Output Overvoltage Protection
• Overtemperature Protection
• Available Package: 3 mm x 3 mm QFN-16 lead package
A high-performance peak-current mode control system is used to deliver a fast
response to sudden line and load changes
2.1.1.1
The MCP16321 Evaluation Board is developed to demonstrate how the MCP16321
buck regulator operates over a wide input voltage and load range. Test points are pro-
vided for input and output voltage, allowing the MCP16321 Evaluation Board to be con-
nected directly to a system. Test vias are also included to give the user easy access to
the switch, power good, enable and injection nodes for easy evaluation of the device.
There are also ancillary vias provided for attaching extra input and output connections.
The 1A maximum continuous output current is available over the entire V
(6.0V to 24.0V), along with the entire adjustable output range (0.9V to 5.0V).
