General Description
The MAX1556 evaluation kit (EV kit) is a fully assembled
and tested circuit board that evaluates the MAX1556
and MAX1557 PWM step-down DC-DC converters. The
circuit operates from 2.6V to 5.5V. The MAX1556 deliv-
ers up to 1.2A and has pin-selectable 1.8V, 2.5V, 3.3V,
and adjustable output. The MAX1557 delivers up to
600mA and has pin-selectable 1V, 1.3V, 1.5V, and
adjustable output. Each circuit features an on-board
shutdown control.
