ISL9016IRUJWZ-T is a voltage regulator module specially designed to support the high current loads of automotive systems. It is an integrated low-dropout (LDO) linear regulator capable of regulating output voltage as low as 2.5V with maximum output current up to 25A. This compact, highly integrated module EMI filtered modulation circuit offers high efficiency, low ripple and guaranteed ±3% accuracy over temperature. It is suitable to a wide range of applications, from providing low output voltage for processor cores to rejecting the bumps and voltage spike of automotive environment.

Working Principle

The ISL9016IRUJWZ-T uses a linear DC-DC converter topology to regulate voltage levels. The module is set up with two inputs and one output. The output is fed through a power inductor, power capacitor and feedback capacitor, then to the load. A small DC-DC switching regulator is integrated in the module, controlled by an external voltage applied to the Enable/Vref pin. This regulator sets the output voltage of the module according to the reference voltage applied. The reference voltage sets the level of current drive provided by the power transistor.

The internal reference (Vref) is fed through a power inductor, power capacitor and feedback capacitor to modify the power transistor’s output voltage across the output terminals. The gain of the internal linear regulator is adjustable with extemp resistor connected at the RS1and RS2 pins. The output voltage from the module is regulated by changing the level of current drive of the power transistor.

Application Field
