The Corona subsystem design block diagram. The Corona digital input circuit solution is mainly targeted for digital input modules for PLCs, industrial automation, process automation, and motor control applications.ДЇigure 1. The Corona design integrates an octal, digital input translator/serializer ( MAX31911), a data isolation device ( MAX14850), and an H-bridge transformerdriver for isolated power supply ( MAX13256). The reference design accepts high-voltage inputs (36V, max) and features isolated power and data-all integrated into a small form factor. The serialization feature allows a large reduction in the number of optocouplers used for isolation. The Corona ( MAXREFDES12#) subsystem reference design provides the front-end interface circuit of a programmable logic controllerВ (PLC) digital input module. Systems often need many optocouplers for isolating each sensor channel.

In industrial control, industrial automation, motor control, and process automation applications, binary/digital sensors and switches are frequently required.

Universal input mains voltage range: from 90 Vac to 264 Vac frequency from 45 to 65 Hz

The main focus of this demonstration board is the light-load efficiency, achieved through the burst mode function of both PFC and LLC controllers with the self-adaptive deadtime of the L6699, modulated by the internal logic according to the half-bridge node transition times, which allows the maximization of the transformer magnetizing inductance, reducing the primary current at light load operation.ДЄn active high voltage start-up circuitry based on a depletion MOSFET provides a very fast start-up time and minimizes the residual consumption during normal operation to a negligible level. The output voltage regulation is obtained by modulating the operating frequency. The LLC section uses the L6699, a double-ended controller specific to series-resonant half-bridge topology. The PFC section uses a proprietary LM-FOT (line-modulated fixed-off-time) that allows control methodology at fixed frequency operation for boost PFC converters as long as its operating in CCM. The architecture is based on a two-stage approach: a front-end PFC pre-regulator based on a CCM (continuous conduction mode) boost PFC controller using the L4984, and a downstream LLC resonant half-bridge converter, designed around the L6699.ДЄt the secondary side, synchronous rectification is implemented by means of the SRK2001 that assures a very high rectification efficiency with consequent small Heat Sink required.

The EVL400W-EUPL7 demonstration board with an output of 12V at 33A, 400W AC/DC converter, tailored for the typical specification of an AC/DC adapter with wide input mains range, very low power consumption at light load and good average efficiency.
