MAX1761EVKIT：MAX1761评估板
The MAX1761 evaluation kit (EV kit) demonstrates a standard 2A application circuit. This DC-DC converter steps down high-voltage batteries and/or AC adapters, generating a precision, low-voltage rail for use as chipset, I/O, and other low-voltage supplies in notebook computers and PDAs.
The MAX1761 EV kit provides dual 1.8V and 2.5V output voltages from a +5V to +20V battery input range. It delivers up to a 2A output current for each output with greater than 90% efficiency. The EV kit operates at 300kHz switching frequency and has superior line- and load-transient response.
This EV kit is a fully assembled and tested circuit board. It also allows the evaluation of other output voltages in the 1.0V to 5.5V range by changing feedback resistors R1–R4.
