电源管理IC开发工具 MCP1601 Buck Reg Eval Brd
The is a MCP1601 500mA buck regulator evaluation board, demonstrates MCP1601 synchronous buck regulator, developed for battery powered applications as well as distributed power applications. Both the high side buck P-channel and the low side N-channel switches are integrated within the device. The integrated synchronous switch makes the MCP1601 very efficient, even when converting unregulated input voltages to low voltage, fixed outputs. The MCP1601 evaluation board is capable of operation over the entire 2.7V to 5.5V input range of the MCP1601 device. Two position DIP switches are used, one to select the output voltage 1.8V, 2.05V, 2.45V or 3.28V and one that turns the MCP1601 on and off with the other position selecting the mode of operation pulse width modulation or pulse frequency modulation. Surface mount test points are used to apply power and load in addition to probing several points in the test circuit.
