ISL6420AIAZ-TK, presented by Intersil Corporation, is a high performance, easy to use, cost efficient, three in one DC/DC converter. It integrates a PWM controller, MOSFET driver and a low ESR OCP (Over Current Protection). The ISL6420AIAZ-TK main purpose is to minimize system design time and number of components. This PWM controller provides a wide range of configurable switching frequencies from 30kHz to 1.6MHz.

In regard to application fields, the ISL6420AIAZ-TK is suitable for general-purpose battery management applications, including backup supplies as well as chargers and microprocessors. In addition, this device is used in boosted converters, gate drivers, battery-operated systems, step-up converters and microcontrollers.

In respect to the working principle, the ISL6420AIAZ-TK PWM converter consists of two main parts: a voltage regulator and an oscillator. The voltage regulator receives its power from the input voltage source. It supplies power to the rest of the converter and sets the output voltage by adjusting the magnitude of the PWM duty cycle. The second part of the converter is an oscillator that contains electronic devices used to generate the PWM signal.

The ISL6420AIAZ-TK includes an OCP circuit that allows the user to set the upper threshold current for the circuit. It is the most easy to configure feature in the device, as it can be tuned by changing the resistance in a single external resistor. This is specially useful when the device is used in battery-operated systems, as it will prevent the battery from receiving too much current.

In conclusion, ISL6420AIAZ-TK is a high performance, easy to use, cost efficient DC/DC converter that integrates a PWM controller, MOSFET driver and a low ESR OCP. This device is suitable for general-purpose battery management applications, including backup supplies as well as chargers, microprocessors, boosted converters, gate drivers, battery-operated systems, step-up converters and microcontrollers. Its working principle consists of two main parts: a voltage regulator and an oscillator. Finally, the OCP circuit of this device is easy to configure and prevents the battery from receiving too much current.
