同步降压DCDC转换器TMI3252，输入电压4.5-18V，输出电流2A，采用COT结构，实现了高压降压的快速瞬态响应，集成低导通电阻的高压侧和低压侧MOSFET，同时内部集成过压保护、软启动、过温保护等功能，

TMI3252在实际应用中，建议采用低ESR的电容，可以提高电路稳定性。

综上所述，西安拓尔微电子的同步降压开关稳压器TMI3252具有集成两个MOSFET和多种保护功能、小尺寸、输出电流2A等性能方面的优势，同时成本低，是Wifi6等网通设备DCDC电源设计的高性价比解决方案

The TMI3252/S/T is a high efficiency 600kHz, Constant on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 2A current. TMI3252/S/T integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor size are achieved with 600kHz switching frequency. It adopts the COT architecture to achieve fast transient responses for high voltage step down applications.
The TMI3252 requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package
