TPS62170QDSGTQ1 Application Field And Working Principle

TPS62170QDSGTQ1 is one of the most common DC-DC Switching Regulators (DC-DC SR) in the market under TPS62170 family. It is a wide-input, small-package, synchronous buck converter which is capable of supplying the core voltage and VCCB/VCCIO low-noise rail of the processor. This family is suitable for both commercial and industrial applications.

TPS62170QDSGTQ1 DC-DC SR can convert input voltage states from 5 V to 20 V. It offers up to 97% of efficiency which could be further increased with the help of an internal dynamic headroom adjustment feature. It also features current-limit protection and adjustable soft-start. With its overall package the solution size and cost can be significantly reduced.

The device has a wide input voltage range from 8V to20V with maximum output current of 1.5A and in a WSON-10EP package solution with low insertion losses. The device integrates high-side and low-side MOSFETs and also includes a 500 mV reference voltage, allowing direct HSL (High Side Low Side) control for higher efficiency. It can be used for any application such as IP cam, embedded system, etc.

The main features of TPS62170QDSGTQ1 DC-DC SR include output voltage up to 1.5A, current limit protection, adjustable soft start, fault protection, high-side and low-side MOSFETs and 500 mV reference voltage. The working principles of TPS62170QDSGTQ1 DC-DC SR can be outlined in the following steps:

The TPS62170QDSGTQ1 step down converter receives the input voltage and then regulates the output voltage. This is done by controlling the flow of current through the switching MOSFETs. The reference voltage is compared to the output voltage to achieve a constant output voltage. The PWM control then turns on or off the switching MOSFETs to manage the amount of current passing through them. When the output voltage reaches a certain level, the device is shut down. The protection circuit prioritizes the external components and avoids any damage that may occur due to any overload of the system.

The TPS62170QDSGTQ1 DC-DC SR component also features short-circuit protection as well as thermal shutdown and overshoot protection, which limits the peak output voltage to protect the system from damage. The device can operate in either PWM or forced PWM mode. The operating frequency is adjustable, ensuring that the switching noise does not create interference with other components.

The TPS62170QDSGTQ1 DC-DC SR component is extensively used to regulate the output voltage of mobile phones, laptops and other low power electronic equipment that require a high degree of efficiency and precise control. The component is also widely used in FPGAs (Field Programmable Gate Arrays) and ASICs (Application Specific Integrated Circuits). The component is highly reliable and provides excellent performance in harsh temperature and operating conditions, making it an ideal choice for applications that require a low-power component that is highly stable and reliable.
