TI公司的LMZM33606是3.5V-36V输入1V-20V输出 6A功率模块,包含了6A DC/DC转换器和功率MOSFET,屏蔽电感和小型封装的无源元件.外接元件仅需要四个,设计过程不需要回路补偿和选择电感元件. 85℃时输出功率高达50W,功率结温–40℃ 到 +125℃,主要用在工业,医疗和测试设备,通用宽VIN稳压器以及反向输出应用.本文介绍了LMZM33606主要特性,功能框图,应用电路以及评估模块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-useintegrated power solution that combines a 6-A DC/DCconverter with power MOSFETs, a shielded inductor,and passives in a low-profile package. This powersolution requires as few as four external componentsand eliminates the loop compensation and inductorpart selection from the design process.
The 16 mm × 10 mm × 4 mm, 41-pin, QFN packageis easy to solder onto a printed circuit board andallows 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, selectableauto or FPWM modes, as well as over-current andover-temperature protection. The LMZM33606 can beconfigured as negative output voltage for invertingapplications.
The LMZM33606 is a full-featured 36-V input, 6-A, synchronous step-down converter with controller, MOSFETs,shielded inductor, and control cir
