• Manufacturer Part Number: ncp1840
• Description: High Current, 8-output Led Driver
• Manufacturer: ON Semiconductor

NCP1840
MAXIMUM PACKAGE POWER DISSIPATION
The power dissipation level is maximum allowed power dissipation for particular package or power dissipation at which the
junction temperature reaches its maximum operating value, whichever is lower.
NCP1840 LAYOUT GUIDELINES
The NCP1840 requires a low-inductance ground.
Charge pump capacitors C0, C1 and C2 and decoupling capacitor CBAT should be as close to the part as possible.
Figure 5. NCP1840 Schematic
GROUND CONNECTION:
Connect pin 6 and pin 15 to the “ground pad” of the IC. (See Figure 6)
Place vias, on the “ground pad”, connecting the GND of the IC directly to the ground plane. (See Figure 6)
