DC2529A

Demonstration circuit 2529A is a dual output synchronous buck converter featuring the LTC®7810ELXE in a 48-lead eLQFP package. Key features of this board include an optional on-board NMOS LDO for DRVCC, jumper for spread-spectrum option, optional resistors for single output dual phase operation, a mode selector that allows the converter to run in CCM, pulse-skipping, adjustable burst clamp or default Burst Mode® operation, SYNC turret for PolyPhase® operation. The input voltage range of this demo board is from 16V to 130V and it uses a sense resistor for overcurrent protection.

• Output voltage VOUT1 is 5V ± 2% (VIN = 16V to 130V, IOUT1 = 0A to 10A, JP4: FCM)
• Output voltage VOUT2 is 12V ± 2% (VIN = 16V to 130V, IOUT2 = 0A to 5A, JP4: FCM)
• Maximum output current IOUT1,MAX is 10A at VIN = 16V to 130V, IOUT1,MAX
• Maximum output current IOUT2,MAX is 5A at VIN = 16V to 130V, IOUT2,MAX
• Default operating frequency (typical) is 100KHz
• External clock sync frequency range is 75KHz to 750KHz
• Typical full load efficiency is 88.7% (VIN = 48V, VOUT1 = 5V, IOUT1 = 10A0)
