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.
