The Renesas Electronics Corporation ISL9440CIRZ-T is a power management IC featuring four distinct voltage regulator outputs. This component integrates three synchronous buck converters and one linear regulator (LDO) within a single 32-QFN (5x5) package. The synchronous buck converters operate at a switching frequency of 600kHz, offering efficient step-down voltage conversion. The device supports an input voltage range from 4.5V to 24V. This highly integrated solution is suitable for applications in automotive, industrial, and consumer electronics requiring precise and efficient power delivery for multiple rails from a single component. The ISL9440CIRZ-T is supplied on tape and reel for automated assembly.
