WHAT IS THE MCP1642B/D HIGH-CURRENT SYNCHRONOUS BOOST
CONVERTER EVALUATION BOARD?
The MCP1642B/D High-Current Synchronous Boost Converter Evaluation Board is
used to evaluate and demonstrate Microchip’s MCP1642B/D products. The board can
be used to evaluate both package options (MSOP-8 and 2 x 3 mm DFN-8). The
MCP1642B/D High-Current Synchronous Boost Converter Evaluation Board was
developed to help engineers reduce the product design cycle time.
The output voltage for the applications using MCP1642B/D-ADJ can be set using the
external resistor divider.
The converter can be disabled by tying the Enable pin (EN) to ground (GND).
When disabled:
• MCP1642B disconnects the path from input to output for “true-disconnect”.
• MCP1642D connects the input to the output, using the internal P-Channel
MOSFET. During the bypass operation, the P-Channel current limit is disabled,
and the load current should be kept below 800 mA.
When enabled, the MCP1642B/D will regulate the output voltage.
