Datasheet LTC3588-1 (Analog Devices) - 4

LTC3588-1
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings junction temperature range. Note that the maximum ambient temperature may cause permanent damage to the device. Exposure to any Absolute consistent with these specifications is determined by specific operating Maximum Rating condition for extended periods may affect device conditions in conjunction with board layout, the rated package thermal reliability and lifetime. impedance and other environmental factors.
Note 2:
The LTC3588-1 is tested under pulsed load conditions such
Note 3:
The junction temperature (TJ, in °C) is calculated from the ambient that TJ ≈ TA. The LTC3588E-1 is guaranteed to meet specifications temperature (TA, in °C) and power dissipation (PD, in Watts) according from 0°C to 85°C junction temperature. Specifications over the –40°C to the formula: TJ = TA + (PD • θJA), where θJA (in °C/W) is the package to 125°C operating junction temperature range are assured by design, thermal impedance. characterization, and correlation with statistical process controls.
Note 4:
Dynamic supply current is higher due to gate charge being The LTC3588I-1 is guaranteed over the full –40°C to 125°C operating delivered at the switching frequency.
