Intersil – ISL6820x – Easy-to-Use DC/DC Controllers with PMBus Interface Deliver Industry-Leading Transient Performance
Intersil’s new ISL6820x digital hybrid DC/DC controllers provide POL conversions for FPGAs, DSPs, ASICs, processors and general purpose system rails. The ISL68200 with integrated MOSFET drivers can directly drive external MOSFETs, while the ISL68201 with PWM output can be paired with a DrMOS (Integrated Driver and MOSFET) power stage to create a complete voltage regulator solution.
The ISL6820x controllers combine the performance of Intersil’s analog R4 technology with the benefits and flexibility of a digital PMBus interface, providing an easy-to-use, high performance solution.
- Proprietary R4 technology with industry-leading transient response
- Input voltage range of 4.5V to 24V; integrated LDOs for single input rail solution
- Output voltage range of 0.5V to 5.5V with ±0.5% DAC accuracy and remote voltage sense
- Complete configuration with external pin-strap resistors, eliminating complicated NVM programming requirements
- SMBus/PMBus/I2C compatible interface operating at up to 1.25MHz
- Full PowerNavigator support
- Space-saving 4mm x 4mm, 24-lead QFN package
The ISL68201 with PWM output pairs with the ISL99140 DrMOS power stage, a high performance DrMOS power module designed for high frequency power conversion. The part features a three-state PWM input that assists with a robust solution in the event of abnormal operating conditions. The ISL99140 also features a thermal warning output that may be used to notify the power system of an impending thermal fail event, and it supports high efficiency operation at heavy loads and light loads via its diode emulation capability.
Both products have kits, that are great for jump-starting customer designs! The board can be wired into an application or used as standalone hardware:
