MCP1603EV

The MCP1603EV is a MCP1603 buck converter evaluation board designed to demonstrate MCP1603 in an adjustable output voltage configuration. The MCP1603 is a 500mA synchronous buck regulator that features both pulse frequency modulation(PFM) and pulse width modulation (PWM). The PFM mode is used at light loads to improve system efficiency while the 2.0MHz PWM mode is entered at heavy loads. The transition between PFM and PWM modes automatically occurs without any external intervention. The MCP1603 is available in both adjustable parts that require an external divider to set the output voltage and fixed output voltage parts. The high switching speed and TSOT package (1mm maximum height) make the MCP1603 ideal for space constrained applications that require an efficient stepped down voltage.
