denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. (Note 2) VIN = 5V, SHDN = 5V, PWM = 5V unless otherwise noted. PARAMETER CONDITIONS MIN TYP MAX UNITS
TGEN Input High Voltage 1.5 V TGEN Input Low Voltage 0.4 V TGEN Pin Bias Current TGEN = 5V 100 200 µA VREF Pin Voltage IREF = –100µA l 1.96 2 2.04 V VREF Pin Voltage Line Regulation 3V < VIN < 40V 0.03 %/V Gate Turn-On Delay CLOAD = 1nF Between ISP and TG 200 ns Gate Turn-Off Delay CLOAD = 1nF Between ISP and TG 200 ns Top Gate Drive VGS (VISP – VTG) VISP = 24V, TGEN = 5V 7 V PWM = 0V 0 0.3 V
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Absolute maximum voltage at VIN, SHDN, PWM and TGEN pins may cause permanent damage to the device. Exposure to any Absolute is 40V for nonrepetitive 1 second transients and 30V for continuous Maximum Rating condition for extended periods may affect device operation. reliability and lifetime.
Note 4:
This IC includes overtemperature protection that is intended
Note 2:
The LT3518E is guaranteed to meet performance specifications to protect the device during momentary overload conditions. Junction from 0°C to 125°C junction temperature. Specifications over the –40°C temperature will exceed the maximum operating junction temperature to 125°C operating junction temperature range are assured by design, when overtemperature protection is active. Continuous operation above characterization and correlation with statistical process controls. The the specified maximum operating junction temperature may impair device LT3518I is guaranteed over the full –40°C to 125°C operating junction reliability. temperature range. The LT3518H is guaranteed over the full –40°C to 150°C operating junction temperature range. Operating lifetime is derated at junction temperatures greater than 125°C. 3518ff 4 For more information www.linear.com/LT3518 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Operation Applications Information Typical Applications Package Description Revision History Typical Application Related Parts
