UC3825DWTRG4 Application Field and Working Principle

The UC3825DWTRG4 from ON Semiconductor belongs to the PMIC – Voltage Regulators – DC DC Switching Controllers product family. This device is employed as a voltage mode pulse-width modulator that utilizes an improved control scheme over previously available control converts. It is suitable in a wide range of applications, ranging from unregulated inputs to regulated outputs and automotive. Its features include a high frequency oscillator, fast transient response, true differential remote sense amplifier, and more.

Overview of the UC3825DWTRG4 Application Field and Working Principle

  • The UC3825DWTRG4 is a monolithic high-performance power-conversion integrated circuit that is employed as a voltage mode pulse with modulator.
  • The UC3825DWTRG4 can be used in a wide range of applications, from unregulated inputs to regulated outputs, as well as automotive.
  • Its features include a high frequency oscillator, a fast transient response, a true differential remote sense amplifier, and a built-in high-voltage gate driver.
  • The UC3825DWTRG4\'s pulse-width modulator (PWM) works by comparing an internal sawtooth oscillator signal with a control input to produce a pulse width modulation signal output.
  • The UC3825DWTRG4\'s PWM signal is used by the control circuitry to switch the main power switches on and off, thereby regulating the average output voltage.

Inputs & Outputs

The UC3825DWTRG4 is a 3-phase interleaved Pulse-Width Modulator controller that features an adjustable switching frequency up to 250kHz, along with a choice of three different external pulse selection techniques. The device provides a robust main power switch driver output and good noise immunity.

The device has up to four fixed voltage output pins. Designers can select outputs from 0.6v to 13.5v, as well as input voltage from 8v to 30v. This makes the device suitable for multiple power applications.

In addition, the UC3825DWTRG4 can also provide protection features such as over-voltage, under-voltage, and short-circuit protection. An adjustable over-temperature protection is also provided to protect the power switches.

The UC3825DWTRG4 also provides current-mode operation for better current-transient response, improved output counter response, and better AC line feed-forward capability.

Advantages and Benefits

  • Excellent EMI performance
  • Multiple protection functions
  • High frequency oscillator
  • 3-phase interleaved control for motor drive applications
  • Adjustable over temperature protection
  • High-voltage gate driver
  • Excellent start-stop response
  • Good transient response
  • True differential remote sense amplifier
  • Current-mode operation

Conclusion

The UC3825DWTRG4 from ON Semiconductor belongs to the PMIC – Voltage Regulators – DC DC Switching Controllers product family. It is a highly functional monolithic high-performance power-conversion IC that utilizes an improved control scheme over previously available devices. Its features include an adjustable switching frequency up to 250kHz, adjustable voltage outputs from 0.6v to 13.5v, multiple protection functions, an adjustable over-temperature protection, current-mode operation, and more. The UC3825DWTRG4 is an ideal device for a variety of power applications, from motor drives to charge pumps.
