Descripción de TPS7H3302-SP
The TPS7H3302 is a radiation-hardend double data rate (DDR) 3-A termination regulator with built-in VTTREF buffer. The regulator is specifically designed to provide a complete, compact, low-noise solution for space DDR termination applications such as single board computers, solid state recorders, and payload processing.
The TPS7H3302 supports DDR VTT termination applications using DDR, DDR2, DDR3, DDR3L, and DDR4. The fast transient response of the TPS7H3302 VTT regulator allows for a very stable supply during read/write conditions. The TPS7H3302 also includes a built-in VTTREF supply that tracks VTT to further reduce the solution size. To enable simple power sequencing, both an enable input and a power-good output (PGOOD) have been integrated into the TPS7H3302. The enable signal can also be used to discharge VTT during suspend to RAM (S3) power down mode.
