Renesas ISL82xxM - Switching Power Modules

With an integrated controller, power inductor and MOSFETs, the ISL82xxM power modules are optimized for space-constrained and battery-operated applications.

These single-channel, synchronous step-down power modules are capable of delivering 10A or 15A of continuous current. They utilize Renesas’ proprietary R4TM control technology with inherent feed-forward that provides best-in-class fast load and input voltage transient response. The output voltage is fully stable with all-ceramic capacitance while excellent loop stability with internal compensation simplifies design. The ISL82xxM modules only require a few external components to operate with its pin strapping configuration technology, thus providing a very high power density solution.  Renesas’ GHDA technology is a significantly thermally superior structure which allows true use of full output current capability.




Renesas RAA210XXX - Switching Power Modules

Based on the popular fully digital ISL827xM power module series, the RAA210xxx series of fully-encapsulated step-down switching power modules are the first “simple digital” modules.

They have the highest power density advance power solution for ASICs, FPGAs and DSPs, increasing available board space and reducing overall bill of material. The proprietary ChargeMode™ control architecture provides fast transient response and achieves best in class conversion efficiencies. The “simple digital” control technology provides unprecedented ease of design with real time system monitoring capability and control via industry standard PMBus interface

Renesas ISL81601 - Buck-Boost Controller

The ISL81601 is a true bidirectional 4-switch synchronous buck-boost controller for efficient DC-DC power conversion with peak and average current sensing and monitoring at both ends.

It provides cycle-by-cycle current limit in both directions while in buck or boost mode, and generates point-of-load (POL) and voltage rail conversions with peak efficiency up to 99%. The controller uses a proprietary buck-boost algorithm that allows inherent peak current sensing for a robust design and produces the smoothest mode transitions between buck, boost and buck-boost. Its proprietary algorithm reduces low frequency ripple at Vout, ensuring minimal disturbances during line or load transients. The algorithm also ensures predictable ripple voltage under all conditions.

ISL9241 - buck-boost configurable battery charger with SMBus interface and USB power delivery

The ISL9241 is a digitally configurable buck-boost battery charger that can support both Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck Boost (HPBB/Bypass) charging and switch between the modes using firmware control. Bypass mode is also supported using a controller’s firmware, allowing the adapter to provide power directly to the system. The ISL9241 provides the charging function, system bus regulation, and protection features using only NFETs for tablet, ultrabook, and notebook platforms. The advanced Renesas R3™ technology provides a high, light-load efficient Charging mode. The ISL9241 takes input power from a wide range of DC power sources (conventional AC/DC charger adapters, USB Type-C Power ports, travel adapters, etc.) and safely charges battery packs with up to 4-series cell Li-ion batteries.
