LTC3304CRUCM#TRPBF

LTC®3304 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. This 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 VIN with 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. Applications include optical networking, servers, telecom, automotive, industrial, communications, distributed DC power systems (POL), FPGA, ASIC, µP core supplies.
