LTM4630A
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 300kHz to 750kHz. reliability and lifetime.
Note 5:
LTM4630A device is designed to operate from 300kHz to 750kHz
Note 2:
The LTM4630A is tested under pulsed load conditions such that
Note 6:
These parameters are tested at wafer sort. TJ ≈ TA. The LTM4630AE is guaranteed to meet specifications from 0°C to 125°C internal temperature. Specifications over the –40°C to
Note 7:
See Table 1 for Peak Current and Thermal Design Power (TDP) 125°C internal operating temperature range are assured by design, current for different VIN and VOUT. See output current derating curve for characterization and correlation with statistical process controls. The different ambient temperature. LTM4630AI is guaranteed over the full –40°C to 125°C internal operating
Note 8:
Total DC output voltage error includes all errors over temperature: temperature range. Note that the maximum ambient temperature Line and load regulation as well as the tolerance of the integrated top consistent with these specifications is determined by specific operating feedback resistor. conditions in conjunction with board layout, the rated package thermal impedance and other environmental factors.
