The LTC3521IUF#TRPBF from Analog Devices is a highly integrated DC/DC converter solution. It combines a 1A buck-boost converter with two 600mA synchronous buck converters, offering flexibility for various power management needs. The device operates with an input voltage range of 1.8V to 5.5V and features a 1.1MHz switching frequency, which helps minimize the solution footprint by allowing for smaller external components.
Each converter includes features like soft-start and internal compensation for simplified design. The buck converters support 100% duty cycle operation for extended battery life and can operate in either Burst Mode or PWM mode depending on load conditions. The buck-boost converter operates in continuous conduction mode for efficiency and low noise, with Burst Mode available at light loads to reduce standby current.
This IC is designed for applications requiring multiple efficient voltage rails from a single input source. It offers independent power good indicator outputs, thermal shutdown, and overcurrent protection for reliability. The LTC3521IUF#TRPBF is available in a compact 24-pin QFN package, suitable for space-constrained designs.
Key electrical specifications include adjustable output voltages for the buck-boost converter (1.8V to 5.25V) and outputs from 0.6V to VIN for the dual buck converters. The total quiescent current in Burst Mode is a low 30µA, and shutdown current is less than 2µA, making it suitable for battery-powered devices.
