产品概述 返回TOPphs嘉泰姆

The CXEP3473 is a 3A sink/source tracking termination regulator. It is specifically designed for low-cost/ low-external component count systems. The CXEP3473 maintains a high speed operational amplifier that provides fast load transient response and only requires 20μF (2×10μF) of ceramic output capacitance. The CXEP3473 supports remote sensing functions and all features required to power the LPDDR2 /LPDDR3 /DDR IIIL VTT bus termination according to the JEDEC specification. In addition, the CXEP3473includes integrated sleep-state controls placing VTT in High-Z in S3 (suspend to RAM) and soft-off for VTT and VTTREF in S5 (Shutdown). The CXEP3473is available in the thermally efficient TDFN2X2-10.
