General Description The MAX796 MAX797 MAX799 high performance step down DC DC converters with single or dual outputs provide main CPU power in battery powered systems These buck controllers achieve efficiency by using synchronous rectification and Maxim's proprietary Idle Mode™ control scheme to extend battery life at full load up to 10A and no load outputs Excellent dynamic response corrects output transients caused by the latest dynamic clock CPUs within five 300kHz clock cycles Unique bootstrap circuitry drives inexpensive N channel MOSFETs reducing system cost and eliminating the crowbar switching currents found in some PMOS NMOS switch designs The MAX796 MAX799 are specially equipped with a sec ondary feedback input SECFB for transformer based dual output applications This secondary feedback path improves cross regulation of positive MAX796 or nega tive MAX799 auxiliary outputs The MAX797 has a logic controlled and synchronizable fixed frequency pulse width modulating PWM operating mode which reduces noise and RF interference in sensi tive mobile communications and pen entry applications The SKIP override input allows automatic switchover to idle mode operation for high efficiency pulse skipping at light loads or forces fixed frequency mode for lowest noise at all loads The MAX796 MAX797 MAX799 are all available in pin DIP and narrow SO packages See the table below to compare these three converters
