Description

The LTC3307B is a very small, high efficiency, low noise, monolithic synchronous 3A step-down DC/DC converter operating from a 2.25V to 5.5V input supply. Using constant-frequency, peak current mode control at switching frequencies 3MHz to 10MHz and minimum on-time as low as 22ns, this regulator achieves fast transient response with small external components. Silent Switcher architecture minimizes EMI emissions.The LTC3307B 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 over-voltage protection, short-circuit protection, thermal shut-down, clock synchronization, and up to 100% duty-cycle operation for low dropout. The device is available in a low profile 12-lead 2mm × 2mm × 0.74mm LQFN package with exposed pad for low thermal resistance.APPLICATIONSOptical Networking, Servers, TelecomAutomotive, Industrial, CommunicationsDistributed DC Power Systems (POL)FPGA, ASIC, μP Core Supplies
