Overview
Description
The ISL91211BII-EV1Z platform is used to evaluate the high-performance features of the ISL91211B multi-output PMIC, which has four controllers that can configure its power stages for 1+1+1+1 channel outputs. Each channel can deliver up to 5A continuous output current per phase. The ISL91211B uses Renesas' proprietary R5 (Rapid Robust Ripple Regulator) 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 dynamic voltage scaling (DVS) control for all three channels
- Real-time fault protection and monitoring (OC, UV, OV, OT)
- Six-layer board design optimized for thermal performance and efficiency
- Connectors, test points, and jumpers for easy measurements
- Built-in load transient circuits for each output channel
