The ISL78201AVEZ is a high-efficiency, low quiescent current, synchronous DC-DC buck regulator with a wide input voltage range. This device is ideal for a variety of applications, including automotive, industrial and communications. It operates from an input voltage range of 4.5V to 36V and provides rail-to-rail regulated output voltages up to 24V.

The ISL78201AVEZ is a synchronous buck regulator that uses a switch-mode circuit to regulate the output voltage. It uses a pulse width modulation (PWM) technique to control the output voltage, switching between the input and output supply. This is done by turning the switches on and off rapidly, which allows the output voltage to be regulated. The output voltage can be adjusted by changing the duty cycle of the switching waveform.

In order to maximize its efficiency, the ISL78201AVEZ includes a low dropout (LDO) voltage regulator and integrated frequency dithering circuit. The included LDO voltage regulator improves the efficiency of the device by reducing the switching losses and allowing the device to operate at low input voltages. The frequency dithering circuit allows the device to operate at higher efficiencies by reducing the switching frequency when the output voltage is at its minimum.

The ISL78201AVEZ can achieve up to 95% power conversion efficiency and has a wide switching frequency range of 250kHz to 2MHz. It also has a wide variety of protection features including input over voltage protection, output current limit, and over temperature shutdown.

The ISL78201AVEZ is ideal for automotive, industrial and communications applications, where high efficiency and low quiescent current are required. It can be used for many applications, including LED lighting, automotive systems, and point-of-load supplies.
