This device is an evaluation module version of the TPS61231 Buck Regulator, offering precision step-down voltage regulation and comprehensive features to aid the design and development of excellent DC-DC voltage converters.

Application Field:
The TPS61230EVM-089 is designed to meet critical power requirements for both modern and legacy applications. It is an excellent choice for the development of DC-DC voltage converters for automotive, telecommunications, information, and industrial applications. The TPS61230EVM-089 can also be an ideal solution for multi-cell battery-powered systems, using its programmable output voltage control and internal power management control. This makes it ideal for mobile and portable electronic products.

Working Principle:
The TPS61230EVM-089 offers precision voltage regulation by implementing the standard buck-boost converter topology. This topology works by controlling the output voltage by utilizing a feedback loop with an error amplifier, oscillator, synchronous rectifier, and power MOSFET switch.

The oscillator produces a pulse width modulation (PWM) signal with a frequency determined by the frequency control (FC) pin, controlling the duration of the output MOSFET switch’s "on" time. This, in turn, controls the output voltage of the converter. The rectifying diode rectifies the output voltage, providing a low-side voltage reference and routing feedback to the error amplifier. The error amplifier then compares the programmed reference voltage to the low-side voltage reference and adjusts the PWM duty cycle to maintain the reference voltage.

The TPS61230EVM-089 offers a variety of features to aid in the development of DC-DC converters, such as input under-voltage and over-voltage protection, power-on reset and power-on detection, soft-start/soft-stop, programmable current limit threshold, thermal shutdown protection, fast transient response, input voltage noise, and EMI filter reduction functions.

The TPS61230EVM-089 evaluation module is an excellent solution for the development of advanced DC-DC voltage converters. Its excellent performance and comprehensive features make it an ideal choice for a multitude of applications.
