This product offers industry-leading transient response, low noise and easy implementation, and is ideal for powering space-constrained portable and consumer electronics designs. This article provides an overview of the application field and working principle of the TPS560200QDGKTQ1 DC-DC switching regulator.

TPS560200QDGKTQ1 Application Field

The TPS560200QDGKTQ1 is designed for switch mode power supplies (SMPS) with a wide 2.3V to 10V input voltage range and a 3.3V to 8V adjustable output voltage. It can deliver up to 2A continuous output current and is optimized for battery-powered systems. Typical applications include handheld devices, consumer electronic designs, telecommunications and networking equipment, wireless systems, industrial control and automotive applications.

The TPS560200QDGKTQ1 is ideal for applications requiring high efficiency, low noise and high power conversion in small, space-constrained packages. It has a low quiescent current of 55μA, and the programmable soft-start feature simplifies design by reducing output voltage overshoot on start-up. It also has current-limit and short-circuit protection capabilities, enabling it to safely protect the device.

TPS560200QDGKTQ1 Working Principle

The TPS560200QDGKTQ1 is a DC-DC Buck Switching Regulator. It uses the voltage from the input source to power the output voltage with a switch and an inductor operating in an oscillatory manner. The switching frequency of the TPS560200QDGKTQ1 is adjustable from 200kHz to 2.2MHz, enabling the device to optimize its efficiency for any given application.

The TPS560200QDGKTQ1 features an internal error amplifier, which monitors the output voltage and makes adjustments to the switch duty cycle in order to maintain the desired output voltage. The device also has a programmable soft start feature that reduces output voltage overshoot on start up, making it more reliable in powering up applications.

With the low noise and high efficiency, the TPS560200QDGKTQ1 is the perfect choice for powering small size, high efficiency portable and consumer electronic designs.
