AMC2576
ABSOLUTE MAXIMUM RATINGS (Note 1)
Input Voltage, V_IN
45V
ENABLE Pin Input Voltage
Operating Junction Temperature, T_J
-0.3V ≤ V ≤ V_IN
150°C
Storage Temperature Range
-65°C to 150°C
Lead Temperature (soldiering, 10 seconds)
260°C
Note 1:
Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground. Currents are positive into,
negative out of the specified terminal.
Temperature Range
Input Voltage, V_IN
RECOMMENDED OPERATING RATINGS
-40°C ≤ T_J ≤ 125°C

THERMAL DATA
P,PB, DD PACKAGE:
Thermal Resistance-Junction to Tab, θ_JT
Thermal Resistance-Junction to Ambient, θ_JA
Junction Temperature Calculation: T_J = T_A + (P_D × θ _JA).
The θ_JA numbers are guidelines for the thermal performance of the device/pc-board system.
All of the above assume no ambient airflow.
