LMZ22003中文资料具有 20V 最大输入电压的 3A SIMPLE SWITCHER® 电源模块数据手册TI规格书

描述 Description

The LMZ22003 SIMPLE SWITCHER power module is an easy-to-use step-down DC-DC solution capable of driving up to 3-A load. The LMZ22003 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ22003 can accept an input voltage rail between 6 V and 20 V and can deliver an adjustable and highly accurate output voltage as low as 0.8 V. The LMZ22003 only requires two external resistors and three external capacitors to complete the power solution. The LMZ22003 is a reliable and robust design with the following protection features: thermal shutdown, programmable input undervoltage lockout, output overvoltage protection, short circuit protection, output current limit, and this device allows start-up into a prebiased output. The sync input allows synchronization over the 650- to 950-kHz switching frequency range.
