ISL91302BIKZT7AR5856

Voltage Regulators - DC DC Switching Regulators Overview

The ISL91302BIKZT7AR5856 is a discontinued synchronous multiphase buck switching regulator from the ISL91302 series, manufactured by Renesas Electronics Corporation. It supports dual output configurations (3+1 or 2+2 phases) or single output (4-phase) operation with up to 5A per phase current capability. The device operates on a 2.5V to 5.5V supply voltage and features integrated low ON-resistance MOSFETs. It utilizes R5 modulator technology for robust transient response and loop stability without external compensation. The component is housed in a 54-ball WLCSP package with a 0.4mm pin pitch.
