DC2937A

DC2937A is a LT8357 low IQ high power boost converter demonstration board. Demonstration circuit 2937A features the LT®8357 as a 360KHz low IQ, high power boost converter with a 48V output from 10V to 40V input. This demonstration circuit features spread spectrum frequency modulation (SSFM) and split gate driver pins for the high power, high voltage switch. The converter can output 2A and higher. When placed in shutdown, the converter has very low quiescent current, ideal in automotive and other battery-powered applications. Low quiescent current can be achieved with both pulse-skipping and Burst Mode® operation as jumper selections on this demonstration circuit. The LT8357 boost controller IC operates over an input range of 3V to 60V suitable for automotive, telecom and industrial applications.

• Maximum output current is 4A (typ) at 48VOUT, 24VIN, R6 = 0.003ohm, TA = 25°C
• Switching frequency is 430KHz (max) R11 = 90.9Kohm, SSFM On
• Typical efficiency is 95% at 12VIN, 48V 2A output, SSFM off, TA = 25°C
• 5V PGOOD voltage at No FAULT, TA = 25°C
