MAX8550ETI

The MAX8550ETI is one member of the MAX8550 family which is designed as the integrated DDR power-supply solutions for desktops, notebooks, and graphic cards that can be used in (1)DDR I and DDR II memory power supplies; (2)desktop computers; (3)notebooks and desknotes; (4)graphic cards; (5)game consoles; (6)RAID; (7)networking. And also this device offers fully programmable UVP/OVP and skip-mode options ideal in portable applications. Skip mode allows for improved efficiency at lighter loads.

Features of the MAX8550ETI are:(1). Quick-PWM with 100ns Load-Step Response; (2)Up to 95% Efficiency; (3)2V to 28V Input Voltage Range; (4)1.8V/2.5V Fixed or 0.7V to 5.5V Adjustable Output; (5)Up to 600kHz Selectable Switching Frequency; (6)Programmable Current Limit with Foldback Capability; (7)1.7ms Digital Soft-Start and Independent Shutdown; (8)Overvoltage/Undervoltage-Protection Option; (9)Power-Good Window Comparator LDO Section; (10)Fully Integrated VTT and VTTR Capability; (11)VTT has +/-3A Sourcing/Sinking Capability; (12)VTT and VTTR Outputs Track VREFIN / 2; (13)All-Ceramic Output-Capacitor Designs; (14)1.0V to 2.8V Input Voltage Range; (15)Power-Good Window Comparator.

The absolute maximum ratings of the MAX8550ETI can be summarized as:(1)Lead Temperature (soldering, 10s): +300°C;(2)Storage Temperature Range: -65°C to +165°C;(3)Junction Temperature: +150°C;(4)Operating Temperature Range: -40°C to +85°C;(5)REF Short Circuit to GND: Continuous;(6)PGND1, PGND2 to GND: -0.3V to +0.3V;(7)VTTS to GND: -0.3V to (AVDD+0.3V).
