DC/DC Controllers

By Staff Author | January 21, 2004

Maxim introduces the MAX8553/MAX8554 DC-DC step-down controllers that ensure balanced current sourcing and sinking capability of &#177 25 A. The MAX8553 generates 1/2 reference input voltage for VTT and VTTR voltages in DDR and RDRAM memory applications. The VTT and VTTR tracking voltages are maintained within 1% of 1/2 reference input voltage. The MAX8554 is a nontracking step-down controller with a 4.5 V to 28 V input voltage and 0.6 V-feedback threshold voltage. The MAX8553/MAX8554 are available in 16-pin QSOP packages specified for the extended-industrial temperature range (&#150 40&#176C to +85&#176C).
