LTC3308BHV#TRMPBF

LTC3308B is a very small, high efficiency, low noise, monolithic synchronous, step-down DC/DC converter. This device operates in forced continuous or pulse skipping mode for low noise, or 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. Other features include output overvoltage protection, short-circuit protection, thermal shutdown, clock synchronization, and up to 100% duty cycle operation for low dropout. It is widely used in application such as optical networking, servers, telecom, automotive, industrial, communications, distributed DC power systems (POL), FPGA, ASIC, µP core supplies etc.
