EVAL MODULE FOR TPS53126-600

Demonstration circuit DC2527A-A features the LTM4662EY, a dual 15A or single 30A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 4.5V to 20V. With CPWR bias, input voltage can be as low as 2.375V. The output voltage range is 0.6V to 5.5V. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The DC2527A-A offers the TRACK/SS pin allowing the user to program output tracking or soft-start period. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper can select discontinuous conduction mode. MODE_PLLIN pin also allows the LTM4662 to synchronize to an external clock signal (between 250kHz and 1MHz). DC2527A-A has the option of choosing both internal and external compensation circuit for LTM4662. Tying the PHASMD pin to different pins generates certain phases of CLKOUT and Channel 2. The LTM4662 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2527A-A.

Demonstration circuit DC1641 is DC/DC boost converter featuring the LTC3786 constant frequency current mode boost controller. The DC1641A operates over 5V to 24V input and provides over 5A at 6V input voltage and over 9A of output current at 10V input as shown in figure 3. The 350kHz constant frequency operation results in small and efficient circuit. The converter provides high output voltage accuracy (typically ±3%) over wide load range with no minimum load requirement. The demonstration circuit can be easily modified to generate different output voltages.

The LTC3722-1/LTC3722-2 phase-shift PWM controllers provide all of the control and protection functions necessary to implement a high efficiency, zero voltage switched (ZVS), full bridge power converter. Adaptive ZVS circuitry delays the turn-on signals for each MOSFET independent of internal and external component tolerances. Manual delay set mode enables secondary side control operation or direct control of switch turn-on delays. The LTC3722-1/LTC3722-2 feature adjustable synchronous rectifier timing for optimal efficiency. A UVLO program input provides accurate system turn-on and turn-off voltages. The LTC3722-1 features peak current mode control with programmable slope compensation and leading edge blanking, while the LTC3722-2 employs voltage mode control. The LTC3722-1/LTC3722-2 feature extremely low operating and start-up currents. Both devices include a full range of protection features and are available in the 24-pin surface mount GN package.Applications Telecommunications, Infrastructure Power Systems Distributed Power Architectures Server Power Supplies

20A Stackable Single Phase Synchronous Buck Converter Evaluation Module

The LTC3290 is a high voltage boost charge pump with a wide 4.5V to 55V input voltage range that can deliver up to 50mA of output current.When the VSET pin is grounded, the LTC3290 operates as a standard boost charge pump, boosting the VOUT output to a maximum of the sum of the VIN and VAUX input supplies. An external resistor divider can be used on the VOUT, FB and GND pins to set the output voltage to any value between 1V and VIN + VAUX with hysteretic Burst?Mode operation.Alternatively, the device can be configured in a VIN tracking mode, in which the VOUT pin regulates at a fixed offset above the VIN pin. The offset voltage is programmed with external resistors, one from the VOUT to the VSET pin and the other from the FB pin to GND. The maximum output voltage is limited to VIN + VAUX.The LTC3290 is available in a thermally enhanced 10-pin MSOP package.Applications High Efficiency General Purpose High Voltage Boost Supplies?
