Description
General part information
LTC3307A Series
The LTC®3307A 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 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 LTC3307A operates in forced continuous or pulse skip 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. The device is available in a low profile 12-lead 2mm × 2mm × 0.74mm LQFN package with exposed pad for low thermal resistance, and a 16-pin 1.64mm × 1.64mm × 0.5mm WLCSP package.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 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, and a 16-pin 1.64mm × 1.64mm × 0.5mm WLCSP package.For applications that require a faster power-on and transient response, the LTC3307A-1 has reduced power-on time, soft-start time, and higher bandwidth.ApplicationsOptical Networking, Servers, TelecomAutomotive, Industrial, CommunicationsDistributed DC Power Systems (POL)FPGA, ASIC, µP Core SuppliesBattery Operated Systems
