Overview
Description
The ISL91302B is a highly efficient, dual or single output, synchronous multiphase buck switching regulator that can deliver up to 5A per phase continuous output current. The ISL91302B features four integrated power stages and has the capability to assign its power stages to either output. This flexibility allows seamless design-in for a wide range of applications where dual, triple, or quad phase outputs are needed, such as CPU and GPU core power mobile applications. The ISL91302B features integrated low ON-resistance MOSFETs, programmable PWM frequency, and automatic diode emulation, which maximizes efficiency while minimizing the external component count and solution size. Using Renesas’s proprietary R5 modulator technology, the ISL91302B delivers a highly robust power solution capable of ultra-fast transient response, excellent loop stability, and seamless DCM/CCM transitions without requiring external compensation. The ISL91302B is widely configurable through the factory OTP settings. Available features which can be used include: • SPI or I2C interface • External signal telemetry with an internal ADC • Dynamic Voltage Scaling (DVS) with selectable slew rate
