Board enables users to evaluate Renesas buck-boost controller IC
Electronics distributor RS Components (RS), is shipping a board that has been designed for the evaluation of Renesas Electronics’ recently launched ISL81601 bidirectional buck-boost controller IC.

The ISL81601EVAL1Z evaluation board integrates the ISL81601, which is a true bidirectional four-switch 60V high-voltage synchronous buck-boost controller. Employing the silicon vendor’s proprietary buck-boost algorithms, the chip offers peak and average current sensing and monitoring in either buck or boost mode. It can ensure high reliability for end equipment by providing cycle-by-cycle current limiting in fast transient conditions – in both directions and at either the line or load end.

Other capabilities of the ISL81601 include external soft-start, independent enable functions, and a wide series of protection features, including under-voltage, over-voltage/current and over-temperature. The IC also delivers peak efficiency of up to 99% for point-of-load (POL) and voltage rail conversion; a gate driver that delivers up to 20A for the buck-boost output; and programmable switching frequency ranging from 100 to 600kHz, which aids optimisation of inductor size.

The evaluation board offers a very wide input range – from 9V to 60V – and both the board and the IC are suitable for a wide selection of applications such as battery backup, USB Type-C power supplies and chargers, and redundant power supplies.

In addition, due to the chip’s wide input-voltage range, it is expected to be commonly used in telecommunications applications, battery-powered industrial equipment and in the automotive aftermarket, as well as other applications in medical equipment, robots and drones, and security surveillance markets.
