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?

Demonstration circuit 2616A-D features a polyphase design using the LTM4647EY, a 30A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 6V to 15V. To use DC2616A-D for input voltage range from 4.7V to 6V, connect INTVCC to SVIN (change R22, R42, R55, R68 from OPT to 0Ω), DRVCC to VIN (change R21, R38, R52, R65 from 0Ω to OPT, R2, R39, R53, R66 from OPT to 0Ω). The output voltage range is 0.6V to 1.8V. The DC2616A-D can deliver a nominal 120A output current with four LTM4647 modules in parallel. 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 pulseskipping mode for noise sensitive applications or burst mode operation in less noise sensitive applications. The MODE_PLLIN pin also allows the LTM4647 to synchronize to an external clock signal. The phase shift between two adjacent phases is 90 degrees. DC2616A-D has the option of choosing both internal and external compensation circuit for LTM4647. The LTM4647 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2616A-D.
