DC2006A-A

DC2006A-A demonstration circuit is a multiphase high power, high voltage step-up DC/DC converter featuring the LTC®3862-2 boost controller. This demo board converts a 6V to 36V input voltage to a 50V output at up to 10A with four phases by utilizing and synchronizing two LTC3862-2 controller IC’s. The DC2006A-A supports three ways of biasing the LTC3862-2 controllers IC’s by directly from the input voltage, or from a low power switching power supply or from an LDO regulator. An onboard SEPIC power supply can provide a stable 10V bias voltage for both LTC3862-2 controllers over the wide varying input voltage. This allows the use of either logic level or standard level MOSFETs, even when the input voltage drops far below the 10V set-point, which is useful in wide varying input applications.

• Typical switching frequency 200KHz
• Typical output ripple of 120mV at (VOUT, 50V) ILOAD = 5A
• 97% typical efficiency
