LTC3307AEV#TRMPBF

LTC3307A is a very small, high efficiency, low noise, monolithic synchronous step-down DC/DC converter. Using constant frequency, peak current mode control at switching frequencies 1MHz to 3MHz and minimum on-time as low as 22ns, this regulator achieves fast transient response with small external components. Silent Switcher architecture minimizes EMI emissions. 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 upto 100% duty cycle operation for low dropout. It is used in application such as optical networking, servers, telecom, automotive, industrial, communications, distributed DC power systems (POL), FPGA, ASIC, µP core supplies, battery operated systems etc.
