The ISL95338IRTZ-T is a ultra-low voltage DC/DC converter that combines a DC/DC controller and two high and low-side power MOSFETs in a 4 mm x 4 mm QFN package. It is designed to operate in ultra-low voltage applications where rail voltages as low as 0.6V are not uncommon. The Ultra-Low Voltage DC/DC Converter works by using a buck-boost topology that allows it to handle input voltages above and below the output voltage. The combination of a buck and boost topology, combined with the inherent self-protection features like short-circuit protection, thermal shutdown and over-current protection make the ISL95338IRTZ-T the ideal choice for ultra-low voltage applications.

The ISL95338IRTZ-T can be used to provide power to a wide range of ultrasmall consumer devices such as wearables, mobile phones, and medical devices. It is also capable of powering FPGAs, MCUs, MEMs and LEDs. The device operates in a wide input voltage range of 0.8V to 5.5V, while using as little as 8.5 mA/MHz quiescent current. It has an adjustable switching frequency of 1 MHz to 2.25 MHz. The device is designed to provide a wide range of output voltages, adjustable from 0.6V to 3.3V. It also features a flexible loop compensation for stability and high output ripple rejection.

The ISL95338IRTZ-T combination of features and flexible operation mode makes it an easy to use and reliable solution for a wide range of ultra-low-voltage applications. The device is capable of automatically entering shutdown mode if the input voltage falls below the dropout voltage, thereby providing enhanced system reliability. The low-current under-voltage lockout (UVLO) ensure increased system reliability and helps to protect from damage due to drops in input voltage. The device has a low quiescent current of 8.5 mA/MHz, minimizing power consumption and enabling the design of ultra-low-power end-products. It also has a high efficiency of up to 96.3%, providing the designers with the flexibility to design robust power solutions in small form factors.
