TI TPS53626RSMR 2-Phase D-CAP+™ Step-Down Controller

In today's high performance computing and server applications, power management has become a critical aspect of system design. As a world-renowned distributor of electronic components, Shenzhen Mingjiada Electronics Co., Ltd. has a stable long-term supply of TI TPS53626RSMR 2-phase D-CAP+™ buck controllers, which are designed to optimise power supply for VR13 CPU VCORE and DDR memory.

Product Description Of TPS53626RSMR

TPS53626RSMR is a driverless, VR13 SVID compliant, synchronous buck controller. Advanced control features such as D-CAP+ architecture with overlapping pulse support undershoot reduction (USR) and overshoot reduction (OSR) provide fast transient response, lowest output capacitance and high efficiency.

TPS53626RSMR also supports single-phase operation in CCM or DCM for light-load efficiency boost. The TPS53626RSMR device integrates a full set of VR13 I/O features including VR_READY (PGOOD), ALERT and VR_HOT. The SVID interface address allows programming from 00h to 07h. Adjustable control of VOUT slew rate can be programmed as high as 20mV/uS.

TPS53626RSMR device package is a space saving, thermally enhanced 32-pin VQFN package that operates from –40°C to 105°C.
