Development of Micro Power Sources with High Efficiency
Abstract : A monolithic DC DC converter with power integration is archieved using two-loop control structure of current mode and voltage mode, combined with key technologies such as peak current sampling etc.Key technologies such as peak current sampling and slope compensation etc greatly improve stability of the system and ability of system to fast respond to transient. Micromodule measuring 19mm*19mm*5.5mm is made combined with pattern optimizing layout such as DC DC anti-EMI, and based on integrated packaging case of AIN. The range of input voltage is from 5.5V to 7V.Output current is great than 5A. The maximum operating efficiency is greater than 92.50%.
Key Words : current mode ,peak current sampling, AIN integrated packaging case ,micro power module.
