Analog Devices Inc. LTC3306 Synchronous Step-Down Regulators are very small, high efficiency, low noise, monolithic synchronous step-down DC/DC converters capable of providing a 1.75A (maximum) average output current from a 2.25V to 5.5V input supply. These regulators achieve fast transient responses and precise regulation in a tiny solution size utilizing a constant frequency, a peak current mode control at 2MHz switching frequency, and a minimum on-time of 22ns. Available modes include Forced Continuous Mode for lower noise or Low Ripple Burst Mode® operation for higher efficiency at light loads.
Available with an external resistor programmable output or fixed output voltages from 500mV to 3.65V in 50mV increments, the LTC3306 provides 100% duty cycle operation that delivers very low dropout voltage. Other features include a high-precision PGOOD output, a
precision enable threshold, output overvoltage protection, thermal shutdown, and output short-circuit protection. The Analog Devices Inc. LTC3306 Synchronous Step-Down Regulators are available in a 6-pin 1.6mm × 1mm, 0.5mm pitch WLCSP package.
