The LTC3533EDE#TRPBF is an ultra-low cost, high efficiency controller/regulator, manufactured by Analog Devices, in a PMIC; DC/DC converter package form. It provides up to 25 mO current sinking control of the internal N-channel MOSFETs to ensure efficient control, even in light load conditions. It features an ultra-wide input voltage range of 1.8 V to 5.5 V and output voltage range of 1.8 V to 5.25 V. It is available in a 14-lead, thermally enhanced DFN package. Its features include short-circuit, overtemperature, and UVLO protection, adjustable soft start, and full diagnostics. It is suitable for powering applications that require 1.8 V to 5.25 V, regulated voltage with very low noise, EMI, and ripple.
