Vishay Intertechnology broadened its offering of microBUCK synchronous buck regulators with a new family of 15 A, 25 A, and 40 A devices featuring input voltages from 4.5 V to 20 V in the thermally enhanced 5×7 mm PowerPAK MLP34-57 package. Delivering increased power density and transient response compared to previous-generation devices, Vishay Siliconix SiC45x family regulators offer PMBus 1.3 compliance for power system telemetry.
The regulators offer low operating current in idle mode, enabling peak efficiency up to 98 % and reducing power losses. Intended to simplify the design of high performance point of load (POL) converters, the integrated devices require minimal external components for configuration and loop compensation.
SiC45x family regulators are internally compensated over the entire VIN and VOUT range of operation. Highly configurable, the devices combine their wide input voltage range with an adjustable output voltage from 0.3 V to 12 V. The extremely versatile regulators are ideal for a wide range of applications, including POL converters in cloud computing, enterprise servers, and industrial computers, in addition to networking, telecom, and storage systems.
