It steps down a 3 V to 5.6 V input rail to a regulated positive output using a transistor-driver stage and external MOSFETs. The part integrates current limit, enable, and power-good control features, and supports clock synchronization for interleaved operation. ## Switching frequency and inductor sizing The switching frequency is programmable from 150 kHz to 1.5 MHz. A lower frequency (150 kHz) reduces switching losses and suits higher step-down ratios, while 1.5 MHz shrinks the inductor and output capacitor but demands tighter layout to keep switching-node ringing under control. The 90% maximum duty cycle gives headroom for low-dropout operation near the input rail. ## Two-phase interleaved output With two outputs and clock sync, the ISL8120IRZ can be configured as two independent single-phase regulators or as a single dual-phase rail. Interleaved two-phase operation cancels input ripple current and reduces output voltage ripple. ## Temperature grade and environment Rated for -40°C to 85°C ambient, the ISL8120IRZ fits industrial control, telecom line cards, base station power, and general-purpose point-of-load converters. ## Lifecycle and sourcing The ISL8120IRZ is listed as Active with ROHS3 compliance. For current designs this means no imminent obsolescence risk.","metaTitle":"ISL8120IRZ Dual-Output Buck Controller, 150kHz-1.5MHz","metaDescription":"ISL8120IRZ step-down buck controller from Renesas.
