LTM4630
ELECTRICAL CHARACTERISTICS 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:
The switching frequency is programmable from 400kHz to 750kHz. reliability and lifetime.
Note 5:
LTM4630 device is designed to operate from 400kHz to 750kHz
Note 2:
The LTM4630 is tested under pulsed load conditions such that
Note 6:
These parameters are tested at wafer sort. TJ ≈ TA. The LTM4630E is guaranteed to meet specifications from 0°C to 125°C internal temperature. Specifications over the –40°C to
Note 7:
See output current derating curves for different VIN, VOUT and TA. 125°C internal operating temperature range are assured by design, characterization and correlation with statistical process controls. The LTM4630I 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.
