LTM4650A ELECTRICAL CHARACTERISTICSNote 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 250kHz to 780kHz. reliability and lifetime. Note 5: LTM4650A device is designed to operate from 250kHz to 780kHz Note 2: The LTM4650A is tested under pulsed load conditions such that Note 6: These parameters are tested at wafer sort. TJ ≈ TA. The LTM4650AE 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 curve for different ambient 125°C internal operating temperature range are assured by design, temperature. characterization and correlation with statistical process controls. The Note 8: Total DC output voltage error includes all errors over LTM4650AI is guaranteed over the full –40°C to 125°C internal operating temperature – reference, line and load regulation as well as the tolerance temperature range. Note that the maximum ambient temperature of the integrated top feedback resistor. consistent with these specifications is determined by specific operating conditions in conjunction with board layout, the rated package thermal impedance and other environmental factors. 4650afb For more information www.linear.com/LTM4650A 5
