Working Principle of TPS57040QDRCRQ1

The TPS57040QDRCRQ1 device implements a synchronous buck converter in order to convert the input voltage to any specified output voltage. The device uses external MOSFETs for the internal switch, allowing for higher efficiency and higher voltage conversion ratios. Furthermore, it features pulse-by-pulse current limit and input current limit, improving transient response and ensuring complete safety at all times.

The device automatically enters pulse-skipping mode if the output load is lower than the peak inductor current. This leads to improved efficiency under light load conditions. Furthermore, the device offers an adjustable switching frequency, allowing customers to optimize the system to their own requirements. The frequency of the device can be selected between 250kHz and 2.2MHz.

The integrated wide input voltage range (1.7V to 5.5V) allows the device to be used with one-cell Li-Ion battery, three-cell Alkaline batteries and other power supplies. The built-in under-voltage lockout and foldback current limit feature further improve the safety of the system.
