ncp5378 ON Semiconductor, ncp5378 Datasheet - Page 4

• Manufacturer Part Number: ncp5378
• Description: Single Phase Synchronous Buck Controller With Integrated Gate Drivers And Programmable Dac
• Manufacturer: ON Semiconductor

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
*All signals referenced to GND unless noted otherwise.
*The maximum package power dissipation must be observed.
1. JESD 51−5 (1S2P Direct−Attach Method) with 0 LFM
2. Operation at −40°C to 0°C guaranteed by design, not production tested.
