产品详情

The LTC3306 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.

The LTC3306 is available with an external resistor programmable output or with fixed output voltages from 500mV to 3.65V in 50mV increments, and 100% duty cycle operation delivers very low drop out voltage.

Other features include a high precision PGOOD output, a precision enable threshold, output overvoltage protection, thermal shutdown, and output short-circuit protection. This device is available in a 6-pin 1.6mm × 1mm, 0.5mm pitch WLCSP package.
