LTC3306 Datasheet 1.75a Synchronous Step-down Regulator

Manufacturer: Analog Devices

Overview: LTC3306 1.75A Synchronous Step-Down Regulator in 1.6mm × 1mm.

General Description

The LTC®3306 is a very small, high efficiency, low noise, monolithic synchronous step-down DC/DC converter capable of providing as much as 1.75A average output current from a 2.25V to 5.5V input supply.

Using constant frequency, peak current mode control at 2MHz switching frequency, and with a minimum on-time of 22ns, this regulator achieves fast transient response and precise regulation in an extremely small solution size.

The LTC3306 is available in forced continuous mode for lower noise, or low-ripple Burst Mode operation for higher efficiency at light load.
