Overview

Description

The ISL91301BII-L-EV1Z and ISL91301BII-H-EV1Z platforms allow quick evaluation of the high performance features of the ISL91301B multi-output PMIC, which has three controllers capable of configuring its power stages for 1+1+1+1 channel outputs. Each channel can deliver up to 4A per phase continuous output current for 2.8V ~ 5.5V supply voltage, or 3A per phase current for wider 2.5V ~ 5.5V supply voltage.

The ISL91301B uses the Renesas proprietary R5 modulator technology to maintain accurate voltage regulation while providing excellent efficiency and transient response. It also supports the standard I2C and SPI communication protocols, ideal for systems using a single-cell battery.

Features

  • Small, compact design
  • Supports both I2C and SPI bus communication protocols
  • Adjustable VOUT and independent DVS control for all three channels
  • Real-time fault protection and monitor (OC, UV, OV, OT)
  • Six layer board design optimized for thermal performance and efficiency
