1 mm maximum height TSOT package. The MCP1603 switches at a fixed frequency of 2.0 MHz when operating at a heavy load. This provides a low-noise, small size solution. When operating at light loads, the MCP1603 changes operation to a pulse frequency modulation (PFM) mode to minimize quiescent current drawn from the input source.
WHAT IS THE MCP1603 BUCK CONVERTER EVALUATION BOARD? The MCP1603 Buck Converter Evaluation Board demonstrates the use of Microchip’s MCP1603 device in a step-down application. The evaluation board is a fully functional platform to evaluate the MCP1603 buck regulator over the input voltage, output voltage and current range of the device.
GETTING STARTED The MCP1603 Buck Converter Evaluation Board is fully assembled and tested for evaluating the MCP1603 device. The board requires the use of an external input voltage source of 2.7V to 5.5V and an external load capable of 500 mA.
