The MAX1533 evaluation kit (EV kit) demonstrates the
MAX1533’s standard application circuit. This dual-PWM
synchronous DC-DC converter steps down high-volt-
age batteries and/or AC adapters, generating main
supplies for notebook computers. The MAX1533 EV kit
operates at 300kHz switching frequency and provides
dual 5V and 3.3V output voltages from a 5V to 24V bat-
tery input range. It delivers up to 5A output current for
the 5V output and 6A for the 3.3V output with 97% effi-
ciency. Both outputs are adjustable between 1V and
5.5V by changing feedback resistors R19–R22.
The MAX1533 also has an internal fixed 3.3V and 5V
linear regulator capable of supplying 100mA. The
MAX1533 EV kit operates at 300kHz switching frequency.
