Typic al Applic ation Circ uit
The typical application circuits (Figures 1 and 2) gener-
ate the 5V/5A and 3.3V/5A main supplies in a notebook
computer. The input supply range is 7V to 24V. Table 1
lists component suppliers.
Detailed Desc ription
The MAX1777/MAX1977/MAX1999 dual-buck, BiCMOS,
switch-mode power-supply controllers generate logic
supply voltages for notebook computers. The
MAX1777/MAX1977/MAX1999 are designed primarily
for battery-powered applications where high-efficiency
and low-quiescent supply current are critical.
The MAX1777 is optimized for highest efficiency with a
5V/200kHz SMPS and a 3.3V/300kHz SMPS, while the
