PMLKBOOSTEVMB is a digital offline intelligent controller designed for DC/DC & AC/DC (Off-Line) SMPS application field. This controller enables accurate current mode control with high speed of fast transient responding. It is specifically designed for the Switch Mode Power Supply (SMPS) applications in the industrial, commercial, consumer, and communication marketplace, with better performance and more features than conventional analog controllers.

Its working principle is based on the principle of hysteresis current mode control as explained below. The input signal to the controller is compared to the threshold values set by the user and a pulse width modulated (PWM) signal is generated in response. The PWM output is then fed to the chopper circuit, where it regulates the current of the voltage outlet. In turn, the current signal is compared to the specified threshold and the output voltage is varied proportionally. This ensures that the current is kept at the regulated level even when the input voltage changes.

PMLKBOOSTEVMB comes with an on-chip chip processor, which converts the analog input signals into a digital format. This digital control can reduce the noise level significantly and achieve better speed performance. Moreover, it has the capability to accurately sense the current waveforms from a wide range of input voltages. This helps to maintain stable system operation.

As a safety measure, PMLKBOOSTEVMB is equipped with multiple protection features such as over voltage, under voltage, linear over-current, highside current-limit, and quiescent current limiting. These features help to avoid system failures due to extreme input voltage or current levels. Additionally, the controller allows for the programming of various parameters, such as the output voltage, current limit, and the voltage regulation, so that the system can be customized depending on the SMPS application field.

PMLKBOOSTEVMB is also equipped with a number of additional features, such as analog loop control, mode selection, active and passive cooling, remote control and monitoring, external input voltage and current control, and an integrated switching circuit. The switching circuit enables fast response time and reduces the number of components required, enabling a reliable and efficient operation.

PMLKBOOSTEVMB is compatible with various types of topologies, such as flyback, forward, and quasi-resonant. It can also support multiple output voltage levels and a wide range of operating frequencies. The controller is also capable of providing power-factor correction, allowing higher efficiency levels.

Overall, PMLKBOOSTEVMB is a reliable and efficient solution for DC/DC & AC/DC (Off-Line) SMPS applications. Its high accuracy, fast response time, and efficient power factor correction make it suitable for a wide range of industrial, commercial, and consumer applications. With the numerous features, high speed performance, and competitive price, the PMLKBOOSTEVMB controller is an ideal choice for DC/DC & AC/DC (Off-Line) SMPS applications.
