LT6658-1.2 Demo Board | Low Noise, High Current, Precision Reference
Analog Devices Inc.
Demonstration circuit 2432B features the LT6658, a precision dual output reference that combines the performance of a low drift low noise reference and a linear regulator. Demonstration circuits are available with 1.25V, 1.8V, 2.5V, 3.0V, 3.3V and 5V output option parts. Both outputs are ideal for driving the precision reference inputs of high resolution ADCs and DACs, even with heavy loading while simultaneously acting as output supplies for powering microcontrollers and other supporting devices. Both outputs have the same precision specifications and A track each other over temperature. Each output can be configured with external resistors to give an output voltage up to 6V.

LTM4636 High Efficiency, PolyPhase 160A Step-Down Power µModule Regulator
Analog Devices Inc.
Demonstration circuit DC2448A-C features a PolyPhase® design using the LTM4636EY, a 40A high efficiency, switch mode step-down power µModule® regulator. The input voltage range is from 4.7V to 15V. When VIN < 5.5V, short PVCC to VIN with R1 = 0Ω, and set R3 = 0Ω and remove R2. The output voltage range is 0.6V to 3.3V. The DC2448A-C can deliver a nominal 160A output current. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper selects pulse-skipping mode for noise sensitive applications or Burst Mode® operation in less noise sensitive applications. The MODE_PLLIN pin also allows the LTM4636 to synchronize to an external clock signal. The phases of the four LTM4636s are 0 degree, 90 degree, 180 degree and 270 degree. DC2448A-C has the option of choosing both internal and external compensation circuit for LTM4636. The LTM4636 datasheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2448A-C.

The LT8645S/LT8646S synchronous step-down regulator features second generation Silent Switcher architecture designed to minimize EMI emissions while delivering high efficiency at high switching frequencies. This includes the integration of bypass capacitors to optimize all the fast current loops inside and make it easy to achieve advertised EMI performance by eliminating layout sensitivity.The fast, clean, low-overshoot switching edges enable high efficiency operation even at high switching frequencies, leading to a small overall solution size. Peak current mode control with a 40ns minimum on-time allows high step-down ratios even at high switching frequencies. The LT8646S has external compensation to enable current sharing and fast transient response at high switching frequencies.Burst Mode? operation enables ultralow standby current consumption, pulse-skipping mode allows full switching frequency at lower output loads, or spread spectrum operation can further reduce EMI emissions.Applications Automotive and Industrial Supplies General Purpose Step-Down GSM Power Supplies
