描述

The MAX1765 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains two separate switching-regulator and linear-regulator circuits. Both circuits are configured for a +3.3V DC-DC output, which provides up to 800mA of current. They also contain a low-dropout (LDO) linear regulator that is configured for a +2.85V output and provides up to 500mA at the output. The two circuits differ only in their package type: the low-power circuit (left side) uses a 16-pin QSOP that can dissipate up to 696mW, while the high-power circuit (right side) uses a 16-pin TSSOP-EP that can dissipate up to 1700mW.

The MAX1765 features an internal N-channel MOSFET switch and a P-channel synchronous rectifier, and a pin-selectable forced pulse-width modulation (PWM) mode. The MAX1765 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.
