Save a space, simplify system of equipment of automobile body electron, frequency and design of inverter grid driver

 

On May 20, 2024, semiconductor of law of Chinese – meaning rolled out converter of DC/DC of synchronism of step-down of class of new series car, new product conduces to save circuit board space, simplify the applied design such as system of automobile body electron, frequency and inverter grid driver.

 

A6983 converter offers agile product type selecting to design staff, this series includes 6 low power comsumption, low noise to be not A6983I of segregation step-down converter and converter of a segregation step-down. These are tall compositive those who spend is odd a circuit of compensation of the buy inside manostat, need very few exterior package only in applying actually, include filter and feedback parts of an apparatus or appliance, a transformer needs when developing application with A6983I.

 

A6983 blame keeps apart type converter to be able to output the load current that is as high as 3A, typical when full load can effect is achieved 88% . Converter of A6983C low power comsumption is to be aimed at light laden operating mode to optimize a design, have the character of high-energy effect and low output ripple, after jockey car system still runs when, but the power consumption that utmost ground reduces car batteries. A6983N is the converter of low a confusion of voices with constant frequency of a switch, but utmost ground reduces converter the output ripple inside whole and laden limits, raise a car to hold the property of the application such as sound system power source. Two kinds of products offer 3.3V, 5.0V and 0.85V to come VIN is adjustable output voltage.

 

A6983I is converter of segregation of a 10W step-down, have former side voltage adjustment function, application is designed need not opto-coupler, suit to use inverter of the drive that make report and car to carry charger very much (the IGBT of OBC) or carborundum (the segregation grid driver of SiC) MOSFET, can adjust accurately former edge outputs voltage. Deputy edge outputs voltage to be circled by transformer number compares a decision.

 

No matter be segregation or blame segregation product, static job electric current all is 25 μ A, province report involves mode electric current under 2 μ A. 3.5V of input voltage limits comes 38V, laden light tolerance is as high as 40V, can prevent advocate the twinkling on power source bus line changes break a system. New product still has output to press protection, overheat protection and interior too the soft function that start. In addition, mode of optional enlarge frequency operation conduces to for noise sensitive model application reduces electromagnetism to disturb (EMI) , and power source is brought normally the foot can realize function of power source sort. A6983I and A6983 support chip and exterior clock synchronism.

 

New series converter uses 3mm X 3mm QFN16 to enclose. The client can apply for the print of A6983 and A6983I freely from ST EStore of store of electron of meaning law semiconductor. Evaluate board STEVAL-A6983CV1 and STEVAL-A6983NV1 A6983, and the assessment of A6983I board STEVAL-L6983IV can help a client start a project quickly, accelerate a project to develop plan.

 

About meaning law semiconductor

The person that meaning law semiconductor has the author of technology of 50 thousand semiconductor and innovation, master semiconductor to supply catenary and advanced production equipment. Regard a semiconductor as perpendicular and integrated manufacturer (IDM) , meaning law semiconductor and two clients, by tens of thousands renown product of a research and development mixes the partner solution, common form builds ecosystem, help them answer all sorts of challenges and new opportunity better, the higher demand that contented world expands to can lasting. A travel that the technology of meaning law semiconductor allows people more intelligence, make power source and energy management more efficient, connective letting the cloud turns equipment application independently more extensive. Acceptance of meaning law semiconductor will be counteracted at realizing carbon 2027 (in limits 1 and 2 inside complete implementation carbon is counteracted, in limits 3 interior divide implementation carbon to counteract) .
