The ISL6341AIRZ is a DC DC Switching Controller manufactured by Jutown Semiconductor Inc. It is specifically designed for use in high power applications needing a high current and low output voltage capability. Designed to optimize power efficiency and accuracy, it operates over a wide input voltage range of 2.5V to 24V and provides up to 4A current for up to a 6V output voltage. The onboard slow start and undervoltage protection guarantee a safe and reliable power supply even under demanding conditions, making the ISL6341AIRZ an ideal choice for both high power and safety-critical applications.

The ISL6341AIRZ features a soft-start mechanism to relieve the system of inrush current when the power is switched on, and an under-voltage lockout (UVLO) feedback mechanism to protect the system from accidental brownouts or overwhelming stress. An adjustable refresh rate and frequency control feature helps to minimize the current ripple and maintain stable output levels regardless of loading conditions, while the programmable output voltage, enabling easy adaptation to changing load needs, makes it suitable for a wider range of applications.

Thanks to its high efficiency PWM control, the ISL6341AIRZ also offers excellent efficiency ratings, with a typically low quiescent current drain of less than 1µA when in Sleep mode, and only 0.2A typical supply current at full load. Furthermore, its high-accuracy output voltage selections, ranging from 0.1V to 6V, make the controller suitable to power many different types of loads with minimal adjustment.

The ISL6341AIRZ packs all these features in an 8-pin SOP package, with an operating temperature range of -40°C to +105°C, making it a great choice for many applications from industrial and automotive, to consumer and home appliances. Its wide/narrow current plimit range (25-100 A) and output ripple cancellation of 2.4 mVp-p make it a great choice for power box and base station applications.

The ISL6341AIRZ is a versatile, high-performance and cost-effective solution for many DC-DC switching applications. It offers the flexibility of an adjustable output voltage, high-efficiency power control, and protection for enhanced reliability and extended life-span. Its small form factor, wide temperature range and high reliability make it well suited for both consumer and industrial applications.
