The LM26480SQ from Texas Instruments is a versatile power management unit (PMU) designed for low-power digital applications. This integrated circuit combines dual 2MHz, 1.5A step-down DC-DC converters (buck regulators) with dual 300mA linear regulators (LDOs), offering a comprehensive power solution.
The buck regulators provide adjustable output voltages from 0.8V to 2V for Buck1 and 1V to 3.3V for Buck2, both capable of delivering up to 1.5A. They operate at a 2MHz PWM switching frequency, achieving up to 96% efficiency and featuring automatic PWM-to-PFM mode change under low loads. The LDOs offer output voltages from 1V to 3.5V with a typical dropout voltage of 25mV.
Key features include individual enable and power good signals, thermal overload protection, current overload protection, and an external power-on-reset function for the buck converters. The device also includes an undervoltage lockout detector to monitor the input supply. The LM26480SQ is housed in a 24-pin WQFN (RTW) package, suitable for surface mounting.
This PMU is compatible with advanced applications processors and FPGAs, making it suitable for powering internal processor functions and I/Os. Its operating temperature range is -40°C to 85°C.
