Product Overview

The MCP1601EV 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.
  • Operates over a 2.7V to 5.5V input range while delivering 500mA of output current
  • One of four output voltages can be selected using the On board switch
  • Low noise fixed frequency PWM operation and light load PFM mode operation
  • External frequency synchronization can be implemented using a 1MHz external clock source
  • ON/OFF switch for evaluating startup and shutdown operation
  • Integrated over temperature protection
  • Integrated soft start circuitry
  • Featured with Small 8 pin MSOP package
  • Integrated under voltage lock out protection
