elecTrical characTerisTics  
Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may affect device  
reliability and lifetime.  
Note 3: Two outputs are tested separately and the same testing condition  
is applied to each output.  
Note 4: The switching frequency is programmable for 400kHz to 750kHz.  
Note 5: LTM4628 device is designed to operate from 400kHz to 750kHz  
Note 6: 100% tested at wafer level.  
Note 2: The LTM4628 is tested under pulsed load conditions such that  
T ≈ T . The LTM4628E is guaranteed to meet specifications from  
J

Note 7: See output current derating curves for different V , V  
and T .

0°C to 125°C internal temperature. Specifications over the –40°C to  
125°C internal operating temperature range are assured by design,  
characterization and correlation with statistical process controls. The  
LTM4628I 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.
