Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Two outputs are tested separately and the same testing condition may cause permanent damage to the device. Exposure to any Absolute is applied to each output. Maximum Rating condition for extended periods may affect device
Note 4:
Although the switching frequency is programmable from 250kHz reliability and lifetime. to 750kHz, the LTM4631 device is designed to operate from 500kHz
Note 2:
The LTM4631 is tested under pulsed load conditions such that to 750kHz for optimized inductor current ripple and efficiency. See the TJ ≈ TA. The LTM4631E is guaranteed to meet specifications from Applications Information section. 0°C to 125°C internal temperature. Specifications over the –40°C to
Note 5:
These parameters are tested at wafer sort. 125°C internal operating temperature range are assured by design,

LTM4631I is guaranteed over the full –40°C to 125°C internal operating temperature range. Note that the maximum ambient temperature consistent with these specifications is determined by specific operating conditions in conjunction with board layout, the rated package thermal impedance and other environmental factors. 4631fb For more information www.linear.com/LTM4631 5 Document Outline Description Typical Application Absolute Maximum Ratings Pin Configuration Electrical Characteristics Typical Performance Characteristics Pin Functions Operation Applications Information Package Description Related Parts Features Applications Typical Application Description Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Simplified Block Diagram Decoupling Requirements Operation Applications Information typical Applications Package Description Revision History Package PHoto Design Resources Related Parts
