DC849B Demonstration Circuit for LTC3499BEDD Synchronous Boost Converter
Quick start guide for the DC849B demo board featuring the LTC3499B synchronous boost converter with reverse battery protection and adjustable 3.3V or 5V output.
Overview
Demonstration circuit 849B showcases the LTC3499BEDD, a 1.2MHz synchronous boost converter with a 750mA switch current limit. The design provides a jumper-selectable 3.3V output at 250mA from a two-cell input or a 5V output at 170mA from either two-cell or Li-Ion batteries. It features integrated reverse battery protection up to -6V, output disconnect, and inrush current limiting. Additional integrated features include peak current limit, soft-start, antiringing control, and thermal shutdown for space-constrained portable applications.
