User's Manual
Description
This NCV8871 evaluation board provides a convenient
way to evaluate a high-frequency current-mode control
SEPIC converter design. The topology uses two inductors.
No additional components are required, other than dc
supplies for the input and enable voltages. An external clock
can be used to synchronize the switching frequency. The
output is rated 12 V / 2 A with a 170 KHz switching
frequency over the typical 6 V to 18 V automotive input
voltage range.
Key Features
• 12 V / 2 A Output
• 170 KHz Switching Frequency (NCV887100)
• Input Undervoltage Lockout
• Internal Soft-Start
• Wide Input Voltage of 6 V to 40 V
• Regulates through 45 V Load Dump Conditions
• External Clock Synchronization up to 1.1 MHz
• Automotive Grade
