TI公司的LMZM33606EVM和LMZM33604EVM是容易使用的集成功率模块解决方案,在小尺寸封装中组合了6A DC/DC转换器和功率MOSFET,屏蔽电感和无源元件.该模块仅需要四个外接元件,在设计过程就不需要回路补偿和电感部分. LMZM33606特性包括电源良好,可调软起动,跟踪,同步,可编UVLO,预偏压起动,可选择自动或FPWM模式以及过流和超温保护.器件还可配置成负电压输出,用于反向应用.器件支持5V,12V,24V,28V输入轨,1V到20V输出电压,满足EN55011电磁辐射,开关频率从350 kHz到2.2 MHz,可以和外部时钟同步.工作环境温度–40°C 到 +105°C,震动和振动测试满足Mil-STD-883D规范.主要用在工业,医疗和测试设备,通用宽VIN调整以及反向输出应用.本文介绍了LMZM33606主要特性,功能框图,典型应用电路图以及评估模块LMZM33606 EVM主要特性,电路图,材料清单和PCB设计图.

 

The LMZM33606 power module is an easy-to-use integrated power solution that combines a 6-A DC/DC converter with power MOSFETs, a shielded inductor, and passives in a low-profile package. This power solution requires as few as four external components and eliminates the loop compensation and inductor part selection from the design process.

The 16 mm × 10 mm × 4 mm, 41-pin, QFN package is easy to solder onto a printed circuit board and allows a compact, low-profile point-of-load design.

The LMZM33606 feature set includes power good, adjustable soft start, tracking, synchronization, programmable UVLO, prebias start-up, selectable auto or FPWM modes, as well as over..
