Figure 2. NCV890201GEVB Board Schematic

Operational Guidelines

1. Connect a dc input voltage, within the 4.5 V to 36 V range, between VIN and GND
2. Connect a load between VOUT and GND
3. Connect a dc enable voltage, within the 4.5 V to 36 V range, between EN and GND
4. Optionally, for external clock synchronization, connect a pulse source between SYNCI and GND. The high state level

should be within the 2 to 6 V range, and the low state level within the -0.3 V to 0.8 V range, with a minimum pulse
width of 40 ns and a frequency within the 1.8 to 2.5 MHz range.
