Description

General part information

MIC5167 Series

The MIC5167 is a high-efficiency, 6A, integrated switch, synchronous buck (step-down) regulator designed for use as a double data rata (DDR) or quad data rate (QDR) terminator. The MIC5167 is optimized for highest efficiency, achieving more than 94% efficiency while still switching at 1MHz over a broad range. The device works with a small 0.4µH inductor and 300µF output capacitor. The ultra-high speed control loop keeps the output voltage within regulation even under extreme transient load swings commonly found in FPGAs and low-voltage ASICs.

The output voltage is controlled externally by input to the VDDQ pin. The output voltage is one-half the voltage applied to the VDDQ pin. The output voltage can be adjusted down to 0.6V to address low voltage power needs. The MIC5167 will source 6A and sink up to 6A.

A window comparator monitors the output voltage and controls the power good output. If the output voltage is outside ±15% limit of VREF the power good is driven low.
