The TPS60202DGSR is an integrated low dropout (LDO) regulator that is specifically designed for portable device power management and portable applications. It is a DC/DC switching regulator with a wide input range from 1.5V to 5.5V and is capable of supplying up to 2A output current. This regulator is highly efficient due to its unique current mode control. It is capable of switching frequencies up to 400kHz.

The TPS60202DGSR provides input under-voltage (UV) protection, output short-circuit protection, and thermal shutdown for added protection against any damage or unexpected events. Moreover, the device has an output voltage accuracy of ±1.5% (1.5V/3V/5V models only) and line/load regulation of 0.3%. It is a great solution when it comes to cost-effective power management solutions.

The TPS60202DGSR has many features that make it a great choice for portable applications including: a low quiescent current of 240μA (typical), low dropout voltage of 1V at 1A (typical), very low startup current of 400nA (typical) and very high efficiency of 93% (typical). The device also supports dynamic voltage scaling (DVS) which allows for maximum flexibility for power management in various applications.

The TPS60202DGSR is typically used in battery-operated, power-sensitive portable applications such as cell phones, personal digital assistants (PDAs), digital cameras, media players, and portable gaming devices. It is also suitable for low power DC-DC conversions, automotive systems, and any application where low voltage, high efficiency, and low quiescent current are desired.

The TPS60202DGSR’s working principle is based on the current mode control topology. It uses a voltage reference, a power FET, and a current sensing resistor, in conjunction with an inner control loop that regulates the output voltage. The on/off switching of the power FET is regulated by current mode control, which results in a fast response to disturbances and accurately regulated output voltage.

Overall, the TPS60202DGSR is a highly efficient and reliable DC/DC switching regulator that is perfect for low power battery-operated applications. It is capable of providing up to 2A output current and features a wide input range, making it a great choice for portable devices. In addition, its integrated protection features provide added security and peace of mind.
