Description
UM3502QA Low-Profile, 600mA, Synchronous Step-Down Converter with Integrated Inductor UM3502QA QFN24 4.0×4.0 General Description The UM3502QA is a complete power conversion solution requiring only two low cost ceramic MLCC caps. Inductor, MOSFETs, synchronous rectifier and control IC are integrated into a tiny 4mm×4mm×1.05mm QFN package. The UM3502QA is engineered to simplify design and to minimize layout constraints. It is an ideal choice to be used to replace less efficient LDO to achieve improved efficiency in space restricted applications. The UM3502QA is capable of delivering 600mA output current over a wide input voltage range from 2.5V to 5.5V. The UM3502QA is a high-efficiency, step-down DC-DC converter with a constant PWM frequency, current mode architecture. The UM3502QA automatically turns off the synchronous rectifier while the inductor current is low, and enters pulse skipping mode at light load condition. This can increase efficiency. The operation frequency is set to...
