ISL9104AIRUJZ-T

The ISL9104AIRUJZ-T is a cutting-edge step-down regulator designed to power low-voltage microprocessors in compact devices. Its versatility is evident in its wide supply voltage range of 2.7V to 6V, making it suitable for a range of power sources, including a single Li+ cell, three NiMH cells, or a regulated 5V input. The device operates at a high switching frequency of 4.3MHz, enabling the use of small external components and contributing to its compact design. With a guaranteed minimum output current of 500mA, the ISL9104AIRUJZ-T maximizes efficiency, particularly under light load conditions, consuming only 20µA of quiescent current. It automatically switches to fixed frequency PWM mode under heavy load conditions, ensuring optimal performance at all times. The internal low ON-resistance P-Channel and N-Channel MOSFETs further enhance system efficiency and reduce the external component count. Additionally, the device features internal digital soft-start, overcurrent protection, and thermal shutdown functions for added safety and reliability. The quick bleeding function effectively discharges the output capacitor when the IC is disabled, providing an extra layer of protection. Packaged in a 1.6x1.6mm µTDFN, the ISL9104AIRUJZ-T offers a comprehensive and compact solution for powering low-voltage microprocessors
