•
符合 VR12.1 串行 VID (SVID) 标准
TPS51623 器件是一款无驱动器、完全符合 SVID 标
准的 VR12.1 降压控制器。高级控制特性（例如 D-
CAP+ 架构）借助重叠脉冲支持下冲衰减 (USR) 和过
冲衰减 (OSR)，可提供快速瞬态响应、最低输出电容
和高效率。TPS51623 器件还支持在 CCM 或 DCM
运行情况下进行单相运行，从而提高轻负载情况下的效
率。TPS51623 器件集成了完整的 VR12.1 I/O 功能，
包括 VR_READY (PGOOD)、ALERT 和 VR_HOT。
SVID 接口地址允许在 0 到 7 的时间范围内进行编程。
当器件在 PS4 模式下运行时，控制器的静态功耗通常
为 0.25mW。VOUT 压摆率和电压定位的可调节控制完
善了 VR12.1 功能。
单相或两相运行
仅支持零负载线路应用
8 位 DAC 输出范围：0.25 V 至 1.52 V
优化了轻负载和重负载条件下的效率
8 级独立的过冲衰减 (OSR) 和下冲衰减 (USR)
无驱动器配置，有助于实现高效的高频开关
支持分立式、电源块、功率级或 DrMOS MOSFET

•
精确可调电压定位
300kHz 至 1MHz 的频率选择
获得专利的 AutoBalance 相位平衡
可选 8 级电流限制
与 TPS51604 FET 栅极驱动器配合使用时，该解决方
案可提供超高速度和低开关损耗。TPS51623 器件与选
定的 TI 功率级产品以及 DrMOS 产品一起使用，可实
现出色效率。TPS51623 器件以 1V 的默认启动电压运
行。通过在设计中添加一个外部电阻分压器，应用可以
覆盖默认启动电压。

5.4 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
