The LTC3676 buck regulators include key functionality such as: a 2.7V to 5.5V input voltage range, a 412mV to VIN output voltage range, PWM with burst, pulse skip and forced continuous modes, selectable oscillator frequencies (2.25MHz as internal default and 1.125MHz I²C selectable), 180° phasing selection on each regulator, SW pin slew rate select for low EMI or high efficiency, and a precision 400mV Enable pin threshold for sequenced startup.
