Evaluation Kit for the MAX1820, MAX1821 (MAX1820EVKIT) (MAX1820EVKIT)
The MAX1820 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains two separate buck switching-regulator circuits. The top circuit utilizes a MAX1820 and is configured for a +0.4V to +3.4V dynamically variable output voltage and provides up to 600mA of guaranteed current. The bottom circuit uses a MAX1821 and is configured for a +1.5V output that provides up to 600mA of guaranteed current. A +2.7VDC to +5.5VDC source could be utilized to power either circuit's input.
The MAX1820/MAX1821 feature an internal MOSFET switch and synchronous rectifier. The MAX1820 EV kit demonstrates low quiescent current and high efficiency up to 97% for maximum battery life. PWM operation at 1MHz allows the use of tiny surface-mount components.
