Overview

The ISL8203MIRZ-T7A is an integrated step-down power module rated for dual 3A output current or 6A current sharing operation. Optimized for generating low output voltages down to 0.8V, the ISL8203MIRZ-T7A is ideal for any low power low voltage applications. The supply voltage range is from 2.85V to 6V. The two channels are 180° out-of-phase for input RMS current and EMI reduction. Each channel is capable of 3A output current. They can be combined to form a single 6A output in current sharing mode. While in current sharing mode, the interleaving of the two channels reduces input and output voltage ripple. The ISL8203MIRZ-T7A offers an independent Power-Good (PG) signal for each channel. When shut down, the ISL8203MIRZ-T7A discharges the output capacitor. Other features include internal digital soft-start, enable for power sequence, overcurrent protection and over-temperature protection. The ISL8203MIRZ-T7A integrates a PWM controller, synchronous switching MOSFETs, inductors and passive components to maximize efficiency and minimize external component count. The ISL8203MIRZ-T7A is available in a thermally-enhanced, compact QFN package.
