Description

General part information

LTC3309A Series

The LTC3309A 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 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.The LTC3309A operates in forced continuous or pulse skip mode for low noise, or the 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. The device is available in a low profile 12-lead 2mm × 2mm × 0.74mm LQFN package with exposed pad for low thermal resistance.For applications that require a faster power on, the LTC3309A-7 has a reduced power on and soft-start time.APPLICATIONSOptical Networking, Servers, TelecomAutomotive, Industrial, CommunicationsDistributed DC Power Systems (POL)FPGA, ASIC, µP Core SuppliesBattery Operated Systems
