LTC3304 Series

The LTC3304 is a very small, high efficiency, low noise, monolithic synchronous 6A step-down DC/DC converter operating from a 2.25V to 5.5V input supply. Using constant frequency, peak current mode control, this regulator achieves fast transient response with small external components.The LTC3304 operates in forced continuous or pulse-skipping mode for low noise, or in low-ripple Burst Mode operation for high efficiency at light loads, ideal for battery-powered systems. The IC regulates output voltages as low as 500mV. The adjustable version operates from 500mV to VINwith two additional external resistors. Other features include output overvoltage protection, short-circuit protection, thermal shutdown, clock synchronization, and up to 100% duty cycle operation for low dropout.The LTC3304 is available in a low profile 2mm × 2mm FCQFN package with exposed pad and side wettable flanks.APPLICATIONSOptical Networking, Servers, TelecomAutomotive, Industrial, CommunicationsDistributed DC Power Systems (POL)FPGA, ASIC, μP Core Supplies
