Vishay Intertechnology Will increase Energy Density for POL Converters With the Business’s Smallest 6 A, 20 A, and 25 A Buck Regulator Modules

Supplied in 10.6 mm by 6.5 mm by 3 mm Package deal, microBRICK® Units Are As much as 69 % Smaller Than Competing Options and Characteristic Large Enter Voltage Ranges From 4.5 V to 60 V

Vishay Intertechnology, Inc. (NYSE: VSH) at this time introduced new 6 A, 20 A, and 25 A microBRICK® synchronous buck regulator modules designed to ship elevated energy density and effectivity for level of load (POL) converters. Supplied in a ten.6 mm by 6.5 mm by 3 mm package deal, the Vishay Siliconix SiC931, SiC951, and SiC967 are the smallest such units in the marketplace — with the bottom top — and have vast enter voltage ranges from 4.5 V to 60 V.

As much as 69 % smaller than different options, the regulator modules launched at this time every provide two excessive efficiency MOSFETs, an inductor, and a controller, with solely minimal exterior parts wanted for configuration and loop compensation. The units’ compact measurement dramatically will increase energy density, whereas their excessive degree of integration reduces design complexity and time to market. The regulators’ controllers eat minimal quiescent present, enabling peak efficiencies of as much as 97 %. In information facilities, the telecom infrastructure, and industrial functions, microBRICK regulators assist scale back vitality consumption by extra effectively delivering energy to FPGAs, ASICs, and SoC core energy provides.

Extremely configurable, the regulators mix their vast enter voltage ranges with adjustable output voltages right down to 0.3 V. As well as, the SiC931 options 4 programmable switching frequencies at 600 kHz, 1 MHz, 1.5 MHz, and a pair of MHz, whereas the SiC967 and SiC951 provide adjustable switching ranges from 100 kHz to 2 MHz and 300 kHz to 1.5 MHz, respectively. All three units provide an adjustable present restrict, whereas the SiC931 options an adjustable gentle begin and the PMBus 1.3 compliant SiC951 helps sequential, monitoring, and simultaneous operation.

The regulator modules present versatile options for a variety of functions, together with POL converters in servers, cloud computing, excessive efficiency computing, and desktop computer systems; industrial automation, motor drives, and instruments; surveillance techniques; client electronics; and 5G telecom tools. For these functions, the SiC951 and SiC967 provide three working modes: pressured steady conduction, ultrasonic, and energy save. The SiC931 supplies pressured steady conduction and energy save modes. In power-saving mode, when the inductor present crosses zero, the management scheme turns off the low facet MOSFET to deploy a diode emulation mode. The switching frequency decreases in proportion to load situations. There isn’t any minimal switching frequency limitation, permitting for the absolute best effectivity at gentle masses.

The units’ fixed on-time (COT) structure delivers ultrafast transient response with minimal output capacitance and tight ripple regulation at very gentle masses. It additionally allows loop stability no matter the kind of output capacitor used, together with low ESR ceramic capacitors. The regulators characteristic a strong safety characteristic set for dependable operation, output overvoltage (OVP) and undervoltage safety (UVP), cycle by cycle overcurrent safety (OCP), brief circuit safety (SCP) with auto retry, over temperature safety (OTP), and an influence good flag.
