DEMO MANUAL DC290 NO-DESIGN SWITCHER LTC1877/LTC1878 Monolithic Synchronous Step-Down Regulator DESCRIPTIO Demonstration circuit DC290 is a constant-frequency voltage, by means of a jumper. The frequency is internally step-down converter using an LTC 1877 or an LTC1878 set at 550kHz or can be synchronized with an external monolithic synchronous regulator. The LTC1878 has an clock. The internal switches allow up to 600mA of output input voltage range of 2.65V < V < 6V and the LTC1877 current in an MSO8 package, providing a space-efficient IN has an input voltage range of 2.65V < V < 10V. The solution for battery-powered applications. The DC supply IN LTC1878 is optimized for low voltage operation and is current is typically only 10m A at no load and less than 1m A ideally suited for single Li-Ion cell or 3-NiCd/NiMH cell in shutdown.
