LTC3307AMPV#TRMPBF

LTC3307AMPV#TRMPBF is a very small, high-efficiency, low-noise, monolithic synchronous 3A step-down DC/DC converter. Using constant frequency, peak current mode control at switching frequencies from 1MHz to 3MHz and a minimum on-time as low as 22ns, this regulator achieves fast transient response with small external components. Silent switcher architecture minimizes EMI emissions. The LTC3307A 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. Applications include optical networking, servers, telecom, automotive, industrial, communications, distributed DC power systems, FPGA, ASIC, microprocessor core supplies, and battery-operated systems.
