This article describes the complete power solution for digital cameras and other complex compact portable applications designed by Linear Technology. The solution uses a family of devices called PMICs (Power Management Integrated Circuits) that greatly simplify the design of complex rechargeable battery power systems.
The text presents 'Design Ideas' for digital cameras and other complex compact portable applications, focusing on complete power solutions. It details how Linear Technology's PMICs (Power Management Integrated Circuits) simplify the management of multiple power sources, such as batteries and USB inputs, in mobile devices.
Specifically, the article describes a solution using the LTC3586 for battery charging with Bat-Track technology and the LT3587 for driving CCDs and LED backlights. It also briefly mentions the LTC3851 regulator.
The device allows for a dimming ratio of 30:1 under these conditions.
The device accepts an input voltage ranging from 4V to 38V.
