The MAX15015A evaluation kit (EV kit) is a fully assembled
and tested PCB that evaluates the MAX15015A
PWM/PFM step-down converter, which integrates a
high-side switch and an LDO regulator. The
MAX15015A EV kit operates over a wide input-voltage
range of 4.5V to 40V and provides up to 1A at
the 3.3V output. The LDO regulator provides up to
50mA at the preset 5V output. The MAX15015A features
undervoltage lockout, overcurrent, and thermal-shutdown
protection.
The MAX15015A normally operates as a PWM converter
and automatically switches to PFM mode at light loads
to improve efficiency. The MAX15015A switching frequency
is preset to 500kHz and features a SYNC input
to provide external frequency synchronization for sensitive
applications. The EV kit provides PCB pads to evaluate
the SYNC and ENABLE features of the
MAX15015A. The EV kit board can also be used to evaluate
the MAX15015B. The MAX15015A can operate
over the automotive temperature range of -40°C to
+125°C.
