LTC3306AACBZ-1.2-R7

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. It is available in forced continuous mode for lower noise, or low-ripple Burst Mode operation for higher efficiency at light load. Other features include a high precision PGOOD output, a precision enable threshold, output overvoltage protection, thermal shutdown, and output short-circuit protection.

• Low ripple Burst Mode® or forced continuous mode of operation
• Wide bandwidth, fast transient response, safely tolerates inductor saturation in overload
• Low shutdown current (1μA), internal compensation, internal soft-start
• Power good output, 1.2V fixed output voltage
• Operating supply voltage range from 2.25 to 5.5V (TA = 25°C, VIN = 4V)
• Discontinuous mode (DCM)/burst mode operation
• Top switch current limit range from 2.5 to 3.0A (TA = 25°C, VIN = 4V)
• Maximum SW leakage current is ±100nA (TA = 25°C, VIN = 4V)
• Soft-start duration range from 0.25 to 3ms (VOUT rising from 0V to PGOOD threshold, TA = 25°C)
• 6-pin WLCSP package, temperature range from -40°C to 125°C
