DC2728A

Demonstration circuit 2728A is a high voltage, dual output boost converter with 12V to 24V input range. The output voltage is adjustable from VIN to 48V. Each output can supply 5A maximum load current. The demo board has a LTC®7880 controller, which is a 60V dual output step-up controller with digital power system management. DC2728A powers up to default settings and produces power based on configuration resistors or its non-volatile memory (NVM) without the need for any serial bus communication. This allows easy evaluation of the DC/DC converter. To fully explore the extensive power system management features of the part, download the GUI software LTpowerPlay® onto your PC and use ADI’s I2C/SMBus/PMBus dongle DC1613A to connect to the board. LTpowerPlay allows the user to reconfigure the part on the-fly and store the configuration in EEPROM, view telemetry of voltage, current, temperature and fault status.

• Typical efficiency of CH0 is 98.1% VIN =12V, VOUT0 = 24V, IOUT0 = 5A
• Typical efficiency of CH1 is 97.1% VIN = 12V, VOUT1 = 48V, IOUT1 = 5A
• Default switching frequency of 150KHz
