TPS82695SIPR Application Field and Working Principle

The TPS82695SIPR DC-DC switching regulator is a high-density, synchronous, step-down, 3A-rated device designed for space-constrained applications. It features an integrated FET, ideal diode, and lockout circuitry. It is integrated with high level features such as input voltage equal to 12V and regulated output voltage equal to 0.8V. The device is used in applications such as automotive, networking, industrial, computing and networking, as well as in high voltage/medium current applications.

The TPS82695SIPR is a synchronous step-down DC to DC converter that operates with a wide input voltage range of 4.1V to 12V and adjusts its output voltage between 0.8V and 12V using integrated feedback regulation. The device is capable of sourcing output current up to 3A and can be programmed with an external resistor. It provides excellent response time, low output voltage noise and small size.

The device features an internal high-gain error amplifier and operates in either forced PWM or forced PFM modes. An integrated integrated under-voltage protection ensures thermal and current protection as well as improved power efficiency. Additionally, the integrated low-side MOSFET provides a low output voltage ripple and low input current.

The TPS82695SIPR also includes a gated oscillator, programmable soft-start, over-temperature protection, as well as internal current limit protection. The device is available in a 3x3mm QFN package and is fully RoHS compliant.

The TPS82695SIPR is an ideal device for applications requiring high efficiency and low noise in a small size. The device is designed to simplify board design by providing integrated features such as over-current protection, over-temperature protection, under-voltage protection, and adjustable output voltage through resistor programming.

The working principle of the TPS82695SIPR DC-DC switching regulator involves three stages: power regulation, current regulation and current switching. During power regulation, the device monitors and adjusts the output voltage using its internal error amplifier and control loop. During current regulation, the device reads the input current and switches the output current on and off to regulate the current. Lastly, during current switching the device uses two FETs to switch the output voltage on/off to minimize power dissipation.

In conclusion, the TPS82695SIPR is a high-efficiency, synchronous, step-down DC to DC converter suitable for space-constrained applications in automotive, networking, industrial and computing. The device is equipped with features such as programmable soft-start, over-temperature protection, under-voltage protection, and adjustable output voltage through resistor programming. Additionally, the device offers excellent response time and low output voltage noise.
