Board User's Manual
Description
The NCV890201 demonstration board provides a convenient way to
evaluate a high-frequency buck converter design. 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; and the board also provides a synchronization
output, enabling it to be used as a master. It is configured for a 3.3 V
output with a 2 MHz switching frequency and a 2.0 A maximum
output current, over the typical 4.5 V to 18 V automotive input voltage
range. In addition, the board regulates up to 36 V thanks to switching
frequency foldback.
Key Features
• 3.3 V Output Voltage

• 2.0 A Current Limit
• Wide Input Voltage of 4.5 V to 36 V
• Regulates through Load Dump Conditions
• External Clock Synchronization up to 2.5 MHz
• Synchronization Output
• Automotive Grade
