Reference design for an remoted energy provide that provides security, floor loop elimination and safety of delicate electronics.
The EV37F82A from Microchip is an remoted energy provide reference design. The MCP1012 15W Reference Design demonstrates the flexibility of the MCP1012 (positioned on the first aspect) to begin up a 15W AC-DC Flyback Converter after which have it commanded by a microcontroller (positioned on the secondary aspect). The MCP1012 15W Reference Design gives a {hardware} and software program platform to judge a novel methodology of remoted secondary aspect management. Two key elements allow the startup and secondary aspect regulation of an remoted energy provide, the Microchip MCP1012 and the Microchip patented built-in magnetic winding transformer constructed by Wurth Digital.
An remoted energy provide is a kind of energy provide that gives electrical isolation between its enter and output. Which means there isn’t any electrical connection between the enter and output sides of the ability provide, and any electrical indicators or noise on one aspect won’t have an effect on the opposite. Such a energy provide is utilized in quite a lot of purposes, together with medical tools, scientific devices, industrial management programs, and different delicate digital units that require electrical isolation for security or efficiency causes.
The reference design has an HV startup functionality of 500V Steady and 700V Transient w/sequence 10K Resistor. It has a programmable low-frequency oscillator (LFO) interval to set startup energy and is ready to settle for exterior PWM instructions from a secondary controller through an isolator. The reference design presents a number of security options together with under-voltage lockout (UVLO) and overvoltage lockout (OVLO) protections, cycle-by-cycle present limiting, and overtemperature safety (thermal shutdown).
This reference design has been examined by Microchip. It comes with required design sources comparable to Gerber recordsdata, schematics, BoM, and so forth.
