The ISL9111EH30Z-T is a DC DC switching device that can be used in a range of applications. It is typically mated with an external power FET to provide a complete DC-DC converter circuit. The device includes protection features such as over voltage, over current and short circuit protection. The device is rated to provide up to 30W of power with a peak efficiency of 95%.

The ISL9111EH30Z-T operates in two modes, typically in fixed frequency mode as a buck converter or in forced continuous current mode as a boost converter. In fixed frequency mode, it uses pulse width modulation (PWM) to regulate the output voltage. The switching frequency can be set with an external resistor or with an input control signal. In forced continuous current mode, the device is operated in Burst Mode and regulates the output voltage by adjusting the duty cycle of the pulses. The device allows for both mode to co-exist such that it can dynamically switch between the two.

The inputs to the ISL9111EH30Z-T are the input voltage, the output voltage, and the mode selection signals. The device includes an internal LDO which can be used to supply the regulators internal logic sections with power. This helps to ensure the device always operate at optimal efficiency.

The ISL9111EH30Z-T is packaged in a 4 pin exposed pad LFCSP package and is suited to high density applications. The device is rated for operation over -40C to +125C temperature range. The device is compatible with both lead free and halogen-free solder processes.

This device is an ideal choice for systems that require a robust DC-DC converter with low power consumption and high efficiency. It can be used in a range of applications including notebook computers, mobile phones, media players, and wireless applications.

The ISL9111EH30Z-T is a highly efficient and reliable device that is capable of regulating the output voltage with a tight accuracy. The device is simple to configure, making it easier to integrate into a range of applications. With its low quiescent current, it is also ideal for battery powered applications that require long run-times. Overall, the device is an excellent choice for DC-DC converters which require high efficiency and low power consumption.
