PWM Controllers

Semtech offers a wide range of efficient Pulse Width Modulation (PWM) controller ICs. Our family of isolated and non-isolated PWM controllers consists of feature-rich, highly integrated solutions which offer design flexibility, lower overall system cost, reduced external BOM and improved reliability.

Our devices support low, medium, and high power non-isolated and isolated DC/DC converters (forward, flyback, push-pull, half-and full-bridge). They enable optimum solutions for systems utilizing distributed power architectures and point-of-load regulation in networking and industrial power supplies, servers, workstations, telecom/datacom, microprocessor-based equipment, portable battery-powered devices and wireless infrastructure products.

Semtech PWM controllers also include EcoSpeed® devices, which incorporate Semtech's advanced, patented adaptive on-time (AOT) control architecture to deliver ultra-fast transient response and very high efficiency across light to full power loads. This unique architecture offers the benefits of conventional converter topologies with optimal tradeoffs for best-in-class performance in next-generation low-power, dynamic point-of-load (POL) applications.
