FAQ

Q1: Is TPS62050 suitable for 3.3V to 1.8V conversion?
Yes, it is very suitable. TPS62050 is a synchronous step-down converter with an input voltage range of 2.5V to 6V, which perfectly covers the common 3.3V power rail. Its output voltage can be accurately set to 1.8V through an external resistor divider to meet the power supply requirements of low-voltage digital circuits. At the same time, the chip has fast transient response and good load regulation characteristics, which is suitable for applications with high requirements for power stability, such as portable devices, wireless modules and embedded systems.

Q2: Does the chip support low-power power saving mode?
It does not support automatic power saving frequency hopping mode (PSM). TPS62050 adopts a fixed frequency PWM control strategy to keep the switching frequency constant even at light load, so the efficiency is relatively low under low load conditions. If the system has higher requirements for light load efficiency, it is recommended to consider TI’s TPS62130, TPS62160 and other series products with power saving mode (PFM/PSM). These devices can automatically reduce the switching frequency at low load, thereby significantly reducing static power consumption and improving overall energy efficiency.
