Description
The MAX1537 evaluation kit (EV kit) demonstrates the MAX1537's standard application circuit. This dual PWM synchronous DC-DC converter steps down high-voltage batteries and/or AC adapters, generating main supplies for notebook computers. The MAX1537 EV kit provides dual 5V and 3.3V output voltages from a 6V to 24V battery input range. It delivers up to 6A output current for the 5V output and 6A for the 3.3V output with 97% efficiency. Both outputs are adjustable between 1V and 5.5V by changing feedback resistors R19-R22.
A transformer on the 5V output generates a 12V auxiliary voltage capable of delivering 150mA. This auxiliary voltage is adjustable between 5V and 23V by changing feedback resistors R17 and R18.
The MAX1537 also has an internal fixed 3.3V and 5V linear regulator both capable of supplying 100mA.
The MAX1537 EV kit operates at 300kHz switching frequency.
