2.1 INTRODUCTION
2.1.1 MCP16301 Features
The MCP16301 device has been developed to provide high input voltage applications
with a precise low voltage regulated rail while operating at high efficiency.
The key features of the MCP16301 include:
• Up to 96% Typical Efficiency
• Input Voltage Range: 4.0V to 30V
• Output Voltage Range: 2.0V to 15V
• 2% Output Voltage Accuracy
• Integrated N-Channel Buck Switch: 460 m
• 600 mA Output Current
• 500 kHz 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): 3.5V
• Overtemperature Protection
• Available Package: SOT23 - 6
A high performance peak-current mode control system is used to deliver fast response
to sudden line and load changes.
2.1.2 MCP16301 600 mA Demo Board Features
The MCP16301 600 mA Demo Board is developed to demonstrate how the MCP16301
device operates over a wide input voltage and load range. Test points are provided for
input and output, allowing the demo board to be connected directly to a system.
A copper via connected to the EN input can be used to turn the MCP16301 on and off
– turning the device on (EN > 1.4V) when the undervoltage lockout threshold is met
(VIN > 3.5V), will enable the device.
