dc524a DC524A LTC3704EMS Demo Board | Positive to Negative Converter, 5V to 15VIN, –5.2VOUT @ 2.5A Demonstration circuit 524 is a positive input to negative output converter featuring the LTC3704 switching controller. The DC524 converts a 5V to 15V input to a –5.2V output and provides up to 2.5A of output current from 5V input. The converter operates at 300kHz with a high efficiency of 89%. The DC524 is set to operate in No RSENSE? mode with input voltages up to 15V. However, DC524 can be modified for higher input voltages with an optional current sense resistor. The circuit features optional soft-start circuitry that can be enabled or disabled with a single jumper. Also, DC524 has a jumper to program either continuous or Burst Mode? operation. The DC524 can be synchronized to an external clock of up to 400kHz. DC524A
