MAX1734EVKIT：MAX1733、MAX1734评估板
The MAX1734 evaluation kit (EV kit) is a fully assembled and tested surface-mount PC board that contains a switching-regulator circuit configured for a +1.8V output. At up to 250mA, it accepts inputs from a +2.7VDC to +5.5VDC source or a 1-cell lithium-ion (Li+) or 2- to 3-cell battery.
The MAX1734 features an internal P-channel MOSFET switch, a synchronous rectifier, logic-controlled shutdown, and digital soft-start to limit startup current. The MAX1734 EV kit provides low quiescent current and efficiency up to 93%, providing maximum battery life. High-frequency operation up to 1.2MHz with a maximum duty cycle of 100% allows the use of tiny surface-mount components. The EV kit can also evaluate the MAX1733 after modifications.
