LT8607

Demonstration Circuit 2565A is a 42V, 0.75A micropower synchronous step-down regulator featuring the LT8607. The demo board is designed for 5V output from a 5.5V to 42V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The LT8607 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes less than 3μA of quiescent current when output is regulated at 5V. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8607 to minimize external components and simplify design.

ADI Key Power Management Features for Versal PRIME XCXM1802 for Minimum Rails / PL Performance

• Proposed Solution implements new LTC3887-1/LTC7051 combo
• LTC3887-1 is a PMBus 2-phase, 2 loop, current mode controller. PMBus commands allow Vin, Vout, current, temperature, and fault status read back.
• LTC7051 is new Silent Switcher 2 ADI MOS capable of delivering increased DC load while switching at higher frequencies. Increased DC load allows for decreased phase count and higher current density. Increased Fsw allows for increase bandwidth and excellent transient response.
• LTC3636 is dual 6A, controlled on-time current mode monolithic (integrated FETs). Provides high performance compact solution for auxiliary rails.
• LT8607 is a compact, high efficiency, high speed 750mA synchronous monolithic.
• LTC3634 is a single chip solution for DDR rails providing VDD, VTT, and Vref in a monolithic solution.

• Alias Free Quad Channel data acquisition
• Alias free dual IEPE-Compatible Vibration Sensor Interface
• Channel Independent Excitation Source and Sensor Bias
• Analog Overvoltage and Undervoltage Protection
• Sensor Frequency Response from DC up to 54 kHz
• Synchronized, Full Bandwidth Data Measurement and Capture
