EVAL-LT8641A-AZ Demo Manual
EVAL-LT8641A-AZ Demo Manual65V, 3.5A/5A Peak SynchronousStep-Down Silent Switcher© 2023 Analog Devices, Inc. All rights reserved. Trademarks and registered trademarks are the property of their respective owners.General DescriptionEvaluation circuit EVAL-LT8641A-AZ is a 65V, 3.5A/5A peak synchronous step-down Silent Switcher ® with spread spectrum frequency modulation featuring the LT ®8641A . The demo board is designed for 5V output from a 5.5V to 65V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The LT8641A is a compact, ultralow emission, high efficiency, high speed synchronous monolithic step-down switching regulator. Top and bottom power switches, compensation components, and other necessary circuits inside the LT8641A minimize external components and simplify design. The special Silent Switcher architecture minimizes EMI emissions. The selectable spread spectrum mode can further improve EMI performance. Ultralow 2.5μA quiescent current in Burst Mode ® operation achieves high efficiency at very light loads. Fast minimum on-time of 35ns enables high V IN to low V OUT conversion at high frequency. The LT8641A switching frequency can be programmed either through oscillator resistor or external clock over a 200kHz to 3MHz range. The default frequency of the evaluation board is 2MHz. The SYNC pin on the evaluation board is grounded by JP1 for low ripple burst mode operation. Move JP1 to PULSE SKIPPING positionto change the operation mode to pulse-skipping operation. Once JP1 is on SPREAD SPECTRUM position, V CC is applied to the SYNC pin for low EMI spread spectrum operation. To synchronize to an external clock, move JP1 to SYNC and apply the external clock to the SYNC turret. Figure 1 shows the efficiency of the circuit at 12V and 24V input in Burst Mode operation. Figure 2 shows EMI performances of the board (with EMI filter). The red lines in Figure 2 are CISPR25 Class5 peak limit. The figure shows that the circuit passes the test with a wide margin. To achieve EMI/EMC performance, as shown in Figure 2, the input EMI filter is required, and the input voltage should be applied at the V EMI turret.The LT8641A data sheet gives a complete description of the part, operation, and application information. Read the data sheet in conjunction with this user guide for EVAL-LT8641A-AZ. The LT8641A is assembled in a 3mm × 4mm plastic QFN package with exposed pad for low thermal resistance. The layout recommendations for low EMI operation and maximum thermal performance are available in the “Low EMI PCB Layout and Thermal Considerations” and “Peak Output Current” sections of the data sheet.Performance Summary Specifications are at T A = 25°C Analog Devices | 2Typical Performance CharacteristicsFigure 1. LT8641A Eval Circuit Efficiency vs. Load Current(2MHz Switching Frequency, Burst Mode)(V EMI = 14V, V OUT = 5V, I OUT = 3.5A, 2MHz Switching Frequency) Analog Devices | 3Quick Start ProcedureThe evaluation board EVAL-LT8641A-AZ is easy to set up to evaluate the performance of the LT8641A. See Figure 3for proper measurement equipment setup and follow this procedure.1.Set an input power supply capable of 65V/5A.2.With power off, connect the input power supplyto V EMI and GND.3.With power off, connect the loads from V OUT toGND.4.Place the voltmeters across the output voltagesense terminals V OUT_SENSE and GND to getaccurate output voltage measurements.5.Turn on the power at the input.Note: Make sure that the input voltage does not exceed 65V.6.Check for proper output voltages. Regulate theoutput at 5.0V (±4%).Note: If there is no output, temporarily disconnect the load to make sure the load is not set too high.7.Once the proper output voltage is established,adjust the load within the operating ranges andobserve the output voltage regulation, ripplevoltage, efficiency, and other parameters. Note: When measuring the input or output voltage ripple, take care to avoid a long ground lead on the oscilloscope probe. Measure the output voltage ripple by touching the probe tip directly across the output capacitor. See Figure 4 for the proper scope technique.8.An external clock can be added to the SYNCterminal when SYNC function is used (JP1 onthe SYNC position). Ensure the chosen RT setsthe LT8641A switching frequency to equal orbelow the lowest SYNC frequency. Refer to thedata sheet section “Synchronization and SpreadSpectrum”.

Auxiliary Code Breakdown
The auxiliary code is the first two characters in the serial number. The first character indicates the year. Years progress or regress in alphabetical order. The series runs from "A" through "V" and the letters "I" and "O" are skipped. The second character indicates significant part changes within a year. Base is "0" and this number advances for each change. In cases where there is a letter in parentheses, this designates the month. This is the last character in the serial number. The series runs from "(A)" through "(M)" and the letter "(I)" is skipped. This designation is only included when identifying a parts change within an auxiliary code.

Compared with CK,T-CK significantly increased the number of grains per spike by8.80%,and significantly reduced the content of amylose by50%;The protein content in P-CK grains significantly decreased by2.10%.In terms of heat damage loss rate,P-CK has the lowest heat damage loss rate.In summary,the combination of organic fertilizer and panicle fertilizer(base fertilizerʒtillering fertilizerʒheading
