Renesas offers a broad portfolio of switching and pulse-width modulation (PWM) controllers optimized to provide high efficiency across the entire load range. The portfolio is comprised of single, dual, triple and quad output controllers with integrated drivers and either voltage- or current-mode architecture.
The ISL81601 and ISL81401 are the industry's only true bidirectional controllers that sense peak current at both ends and provide cycle-by-cycle current limit in both directions while in buck or boost mode.
Designers don't have to be digital power experts to create a 48V mild hybrid design! Support the the rapid adoption of 48V hybrid powertrains for improved emissions and better fuel economy.
The ISL8117 PWM controller provides 98% efficiency, an adjustable switching frequency of up to 2MHz and a minimum on-time of only 40ns, plus it requires no external compensation.
