DC2108A - LTC3897 Demo Board | Sync Boost Controller, 16V ≤ VIN ≤ 55V,Vout = 48V @ 4A to 12A

Demonstration circuit DC2108 is DC/DC boost converter featuring the LTC®3897 constant frequency current mode boost controller. The DC2108A operates over a 16V to 55V input and provides 4A to 12A of output current as shown in Figure 3. The 160kHz (2 •160kHz at the output) constant frequency operation results in a small and efficient circuit. The converter provides high output voltage accuracy (typically ±3%) over a wide load range with no minimum load requirement. The demonstration circuit can be easily modified to generate different output voltages.
