Renesas Electronics Corporation PMIC - PMIC - Power Management - Specialized - ISL6443AIRZ ISL6443AIRZ

The ISL6443AIRZ is a high-performance, triple-output power management controller designed for converting various DC input supplies into required system voltages. It features two out-of-phase PWM controllers operating at a frequency of 300kHz, which helps reduce input current ripple and capacitance requirements. Each output voltage is adjustable down to 0.8V, making it versatile for different applications. This controller includes several protection mechanisms, such as adjustable overcurrent protection, thermal shutdown at +150¬8C, and independent shutdown inputs for each PWM. It also provides a power good signal indicating when the outputs are stable and within specified limits. The device supports a wide input voltage range from 5.6V to 24V and is packaged in a compact 28-lead QFN format, which enhances PCB efficiency. Applications for the ISL6443AIRZ include power supplies for xDSL modems, DSPs, ASICs, FPGAs, and telecom systems, making it suitable for projects requiring reliable multi-output power management solutions.
