General Description
Features
The MAX17501A/MAX17501E evaluation kits (EV kits)
provide proven designs to evaluate the MAX17501A/
MAX17501E high-efficiency, high-voltage, synchronous
step-down DC-DC converters. The EV kits use these
devices to generate a fixed 3.3V, at load currents
up to 500mA, from a 4.5V to 60V input supply. The
MAX17501A supports a PFM control scheme with high
light-load efficiency, while the MAX17501E features a
forced-PWM control scheme that provides constant
switching-frequency operation at all load and line condi-
tions.
Ordering Information appears at end of data sheet.
