DESCRIPTION
The LTC®3302 is a very small, high efficiency, low noise, monolithic synchronous 2A step-down DC/DC converter operating from a 2.25V to 5.5V input supply. Using constant frequency, peak current mode control, this regulator achieves fast transient response with small external ponents.
The LTC3302 operates in forced continuous or pulseskipping mode for low noise, or in low-ripple Burst Mode operation for high efficiency at light loads, ideal for battery-powered systems. The IC regulates output voltages as low as 500m V. The adjustable version operates from 500m V to VIN with two additional external resistors. Other features include output overvoltage protection, short-circuit protection, thermal shutdown, clock synchronization, and up to 100% duty cycle operation for low dropout.
The LTC3302 is available in a low profile 2mm × 2mm FCQFN package with exposed pad and side wettable flanks.
