SMB118 SUMMIT Microelectronics, Inc:, SMB118 Datasheet - Page 14

• Manufacturer Part Number: SMB118
• Description: Six-channel Programmable Dc-dc Power Managers With Battery Charger
• Manufacturer: SUMMIT Microelectronics, Inc:

Note 1: Contact Summit factory for other frequency settings.
Note 2: Voltage, current and frequency accuracies are only guaranteed for factory-programmed settings. Changing any of these parameters from the
values reflected in the customer specific CSIR code will result in inaccuracies exceeding those specified above.
Note 3: The SMB118 and SMB218 devices are not intended to function as a battery pack protector. Battery packs used in conjunction with these
devices need to provide adequate internal protection and to comply with the corresponding battery pack specifications.
Note 4: Guaranteed by Design and Characterization – not 100% tested in Production.
