Analog Devices LTC7810 | Demoboard DC2529A

Beschreibung

Demonstration circuit 2529A is a dual output synchronous buck converter featuring the LTC®7810ELXE in a 48-lead eLQFP package. Key features of this board include: an optional on-board NMOS LDO for DRVCC; jumper for spread-spectrum option; optional resistors for single output dual phase operation; a mode selector that allows the converter to run in CCM, pulse-skipping, adjustable burst clamp or default Burst Mode® operation; SYNC turret for Poly- Phase® operation. The input voltage range of this demo board is from 16V to 130V and it uses a sense resistor for overcurrent protection.The LTC7810 data sheet gives a complete description of the part, operation and application information and must be read in conjunction with this demo manual for DC2529A.
