Overview
MIC5162 Dual Regulator Controller for DDR3 GDDR3/4/5 Memory and High-Speed Bus Termination General Description Features The MIC5162 is a dual regulator controller designed for • Input voltage range: 1.
35V to 6V high speed bus termination.
It offers a simple, low-cost • Up to 7A VTT Current JEDEC compliant solution for terminating high-speed, low• Tracking programmable output voltage digital buses (i.
e.
DDR, DDR2, DDR3, SCSI, GTL, • Wide bandwidth SSTL, HSTL, LV-TTL, Rambus, LV-PECL, LV-ECL, etc).
• Logic controlled enable input The MIC5162 controls two external N-Channel MOSFETs • Requires minimal external components to form two separate regulators.
It operates by switching between either the high-side MOSFET or the low-side • DDR, DDR2, DDR3, memory termination MOSFET depending upon whether the current is being • -40°C < TJ < +125°C sourced to the load or sunk by the regulator.
• JEDEC Compliant Bus Termination for SCSI, GTL, Designed to provide a universal solution for bus SSTL, HSTL, LV-TTL, Rambus, LV-PECL, LV-ECL, etc termination regardless of input voltage, output voltage, or • Tiny MSOP-10 package load current.
The desired MIC5162 output voltage can be programmed by forcing the reference voltage externally to desired voltage.
Applications The MIC5162 operates from an input of 1.
35V to 6V, with • Desktop Computers a second bias supply input required for operation.
It is • Notebook computers available in a tiny MSOP-10 package with operating • Communication systems junction temperature range of -40°C to +125°C.
• Video cards Data sheets and support documentation can be found on Micrel’s web site at: www.
