Do you know about the new synchronous buck regulators in the small 5x5 PowerPAKâ package? Recently, Vishay Intertechnology, Inc. (NYSE: VSH) announced the launch of two new 2 A ~ 12 A microBUCK® series synchronous buck regulators converters with input voltage ranges of 4.5 V to 55 V (SiC476/7/8/9) and 4.5 V to 60 V (SiC466/7/8/9).
Vishay Siliconix devices are packaged in a small 5x5 PowerPAK™ package and contain high-performance n-channel trench MOSFETs and controllers for high efficiency and power density, while internal compensation reduces external component count. The recently released microBUCKâ regulators use the same controller IC and package form factor, while offering a range of MOSFET ratings from which designers can choose the best cost-effective combination.
The recently released voltage regulator has an operating current of only 156µA and a peak efficiency of 98%, allowing designers to reduce power consumption and increase power density. The high efficiency combined with the excellent thermal design of the 5 mm x 5 mm PowerPAK™ package allows the regulator to operate at lower temperatures, improving long-term stability and eliminating the need for a heat sink. microBUCK's wide safe operating area gives designers the flexibility to meet various operating temperature and current requirements. As a result, designers can reduce PCB size, simplify thermal management and reduce system cost.
The SiC466/7/8/9 and SiC476/7/8/9 series voltage regulators have a wide input voltage range and an adjustable output voltage from 24 V to 0.8V, making them suitable for a variety of applications, including industrial and factory automation DC/DC converters, home automation equipment, industrial computing, base station power supplies, 5G network equipment and small cells, wall-mounted transformer regulators, robots, drones, battery management systems, power tools, vending machines, ATM machines and Coin machine.
The new SiC46x family of devices includes 2 A SiC469, 4 A SiC468, 6 A SiC467 and 10 A SiC466, and the new SiC47x family of devices includes 3 A SiC479, 5 A SiC478, 8 A SiC477 and 12 A SiC476. All device footprints are compatible, making it easy for designers to implement expanded application solutions. The voltage regulator is highly configurable, the switching frequency can be adjusted within the range of 100kHz~2MHz, the soft start and current limit can be adjusted, and there are two operating modes: forced continuous operation or energy saving. Both series feature internal compensation and require no external RC network.
The microBUCKâ COT architecture has ultra-fast transient response, requires only a small output capacitor, and can tightly regulate ripple at light loads. Moreover, the regulator maintains loop stability regardless of the type of output capacitor used, including low-ESR ceramic capacitors. The voltage regulator integrates various reliable protection functions, including output overvoltage protection (OVP), output undervoltage protection (UVP), overcurrent circuit protection (OCP), short circuit protection (SCP) with automatic retry, and overtemperature protection (OTP). ) and power good sign.
The SiC466/7/8/9 and SiC476/7/8/9 series are now available for sampling and mass production, with a lead time of 12 weeks. The above is an analysis of the new synchronous buck regulator in a small 5x5 PowerPAKâ package. I hope it can be helpful to everyone.
