LT1610 Linear Technology, LT1610 Datasheet - Page 3

• Manufacturer Part Number: LT1610
• Description: Constant-Current/ Constant-Voltage 1.4MHz Step-Up DC/DC Converter
• Manufacturer: Linear Technology

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LT1610C is guaranteed to meet specified performance from
0 C to 70 C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at – 40 C and 85 C. The
LT1610I is guaranteed to meet the extended temperature limits.
