MAX1820EVKIT

The MAX1820EVKIT 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.

Features of the MAX1820EVKIT are:(1)+2.7V to +5.5V input range;(2)output voltages;(3)dynamically variable output voltage (top circuit);(4)adjustable output voltage through resistive voltage-divider (bottom circuit);(5)internal switch and synchronous rectifier;(6)0.1A (typ) IC shutdown current;(7)1MHz PWM switching frequency;(8)syncable to 13MHz oscillator;(9)normal and forced PWM mode;(10)all surface-mount components;(11)fully assembled and tested.

The MAX1820EVKIT features a selectable clock input.The MAX1820/MAX1821's internal clock can operate the EV kit or the EV kit can be synchronized to an external clock when evaluating the MAX1820X, MAX1820Y, and MAX1821X. The 2-pin jumpers JU3 and JU6 determine the top and bottom circuits' operating clock, respectively.
