ncp5203 ON Semiconductor, ncp5203 Datasheet - Page 4

• Manufacturer Part Number: ncp5203
• Description: 2-in-1 Ddr Power Controller
• Manufacturer: ON Semiconductor

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values
(not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage
may occur and reliability may be affected.
1. All voltages are with respect to AGND (Pin 6) and PGND (Pin 16).
