Beschreibung

The MCP16311/2 is a compact, high-efficiency, fixed-frequency, step-down DC-DCconverter. The integrated features include a high-side and a low-side switch, fixedfrequency, internal compensation, peak current limit and overtemperature protection.This product provides an easy-to-use power supply solution, with a minimum numberof external components.The MCP16311 automatically selects the best operating mode for efficiency,Pulse-Width Modulation (PWM) or Pulse Frequency Modulation (PFM), while theMCP16312 is a PWM-only device. The MCP16311/2 family of devices have a wideinput voltage range (4V to 30V) and a wide output voltage range (2V – 15V). Anintegrated, precise 0.8V reference, combined with an external resistor divider, sets thedesired converter output voltage. The internal reference voltage is controlled duringstart-up, minimizing the output voltage overshoot and the inrush current.The device is available in 8LD MSOP and 2 x 3 mm TDFN packages.The scope of this evaluation board is to demonstrate the features of the MCP16311/2.This chapter provides an overview of the MCP16311/2 Synchronous Buck ConverterEvaluation Board and covers the following topics:• What is the MCP16311/2 Synchronous Buck Converter Evaluation Board?• What the MCP16311/2 Synchronous Buck Converter Evaluation Board Contains

Eigenschaften

The MCP16311/2 Synchronous Buck Converter Evaluation Board has the followingfeatures:

  • Input Voltage Range (VIN): 4V to 30V
  • Fixed Output Voltage: 3.3V and 5.0V
  • Output Current: typically 1A @ 3.3V Output, 12V Input
  • Automatic PFM/PWM Operation for MCP16311, or PWM-only for MCP16312
  • PWM Switching Frequency: 500 kHz
  • Internal Compensation
  • Internal Soft Start
  • Overtemperature protection (if the die temperature exceeds +150°C, 25°Chysteresis)
