TPS5210DWR, an integrated monolithic DC-DC switching controller, has a wide range of applications and is an important member of the PMIC - Voltage Regulators - DC DC Switching Controllers family.

By combining its wide input voltage operating range, high-performance control loop and fast transient response, TPS5210DWR enables low cost, noise immune, high-efficiency solutions for powering voltage regulators and dc-dc converters.

The device features aninternal high-side and low-side MOSFETs, protections of input under-voltage locks and output over-voltage protections, over-current protection, optional heating foldback protections, and a low quiescent-current power-save operation mode.

The typical application of TPS5210DWR is as a step-up converter driving a single-cell Li+ battery and low-dropout regulators. It supports a wide range of input voltages, enabling a single device to be used for multiple applications such as Li+ battery to 1.8V-3.3V and AC adapter to 1.5V-3.3V.

TPS5210DWR can be used to drive either a synchronous or asynchronous step-up DC-DC regulated output power supply with fast transient responses. Synchronous rectification can be used with control loop compensation to maintain high levels of efficiency, while asynchronous rectification can be used to maintain low levels of noise.

The device operates at a constant frequency of up to 2MHz, with an adjustable pulse-width modulated (PWM) mode or the adjustable burst mode operation. Its integrated loop compensation and its adjustable current limit capabilities minimize external components and minimize the design time.

The working principle of TPS5210DWR is that it produces regulated output power by using its input voltage (VIN) to power a switch mode power supply, built around a pair of power MOSFETs, which drives a low-dropout regulator.

It combines a high-side and a low-side MOSFET, with built-in current limit, duty cycle control and power-on reset capabilities. The device can switch its output from low to high in a short time, and its response time is faster than that of linear regulators.

On the basis of this principle, TPS5210DWR can detect the output voltage of the power supply, and it can adjust the PWM duty cycle dynamically to achieve a stable output voltage.

In addition, the device features an internal compensation network to optimize the small signal gain and phase shift. This network provides a certain degree of gain and phase margin to optimize the transient response and loop stability.

TPS5210DWR\'s protection features include input under-voltage lockout, output over-voltage protection, and over-current protection. The device also includes optional heating foldback which reduces the duty cycle when the switched current exceeds a specified level.

In summary, the TPS5210DWR is a dedicated integrated DC DC switching controller for use in automotive, computing, and telecom systems, providing an efficient, noise immune, and low-cost solution for powering voltage regulators and dc-dc converters.
