MAX17501H Datasheet, PDF (1/9 Pages) Maxim Integrated Products – 300kHz Switching Frequency

MAX17501H Evaluation Kit
Evaluate: MAX17501H in TDFN Package
General Description
The MAX17501H EV kit provides a proven design to
evaluate the MAX17501H high-efficiency, high-voltage,
synchronous step-down DC-DC converter in a TDFN
package. The EV kit uses the MAX17501H device to
generate 2.5V at load currents up to 500mA from a 4.5V
to 60V input supply. The MAX17501H features a forced-
PWM control scheme that provides constant switching-
frequency operation at all load and line conditions.
