MAX1763EVKIT：MAX1763评估板
The MAX1763 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed-circuit board (PCB) that contains two separate boost switching-regulator circuits. The first circuit (left side) utilizes a MAX1763 in a 16-pin QSOP package and is configured for a +3.3V output that accepts inputs from a +0.7V to VOUT source and provides up to 1.1A of current. A 1- or 2-cell alkaline battery source can also power the input.
The second circuit (right side) uses a MAX1763 in a high-power 16-pin TSSOP-EP (exposed pad) package, is configured for a +3.3V output, and supplies up to 1.4A of current. It accepts inputs from a +0.7V to +5.5V source, or a 1- or 2-cell alkaline battery can power the input. The right side includes a low-dropout (LDO) linear regulator that draws power from the +3.3V output and provides +2.8V at up to 1A of current.
The MAX1763 features an internal N-channel MOSFET switch, a P-channel MOSFET synchronous rectifier, and pulse-width modulation (PWM) operation for maximum efficiency. The MAX1763 EV kit demonstrates low quiescent current and high efficiency up to 96% for maximum battery life. Operation at 1MHz allows the use of tiny surface-mount components.
