ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the specified internal operating temperature range (Note 2). Specified as each individual output channel. TA = 25°C, VIN = 12V and VRUN1, VRUN2 at 5V unless otherwise noted. Per the typical application in Figure 23. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
GBW Gain Bandwidth Product 3 MHz VTEMP Temp Diode Diode Connected PNP I = 100µA 0.598 V TC Temperature Coefficient –2.0 mV/°C
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:
LTM4620 device is designed to operate from 400kHz to 750kHz
Note 2:
The LTM4620 is tested under pulsed load conditions such that
Note 6:
These parameters are tested at wafer sort. TJ ≈ TA. The LTM4620E 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,
Note 8:
Output current limitations. For 10V ≤ VIN ≤ 16V, the 2.5V output characterization and correlation with statistical process controls. The current needs to be limited to 10A/channel, switching frequency = 750kHz. LTM4620I is guaranteed over the full –40°C to 125°C internal operating Derating curves apply. For 5V ≤ VIN ≤ 9V, the 2.5V output current needs temperature range. The LTM4620MP is tested and guaranteed over the to be limited to 12A/channel, switching frequency = 750kHz. Derating –55°C to 125°C operating temperature range. For output current derating curves apply. All other input and output combinations are 13A/channel at high temperature, please refer to thermal conditions and output with recommended switching frequency included in the efficiency graphs. current derating discussion. Note that the maximum ambient temperature Derating curves apply. consistent with these specifications is determined by specific operating conditions in conjunction with board layout, the rated package thermal impedance and other environmental factors. 4620fc For more information www.linear.com/LTM4620 5 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Typical Performance Characteristics Pin Functions Simplified Block Diagram Decoupling Requirements Operation Applications Information Typical Applications Package Description Package Photo Related Parts
