5 / 36 page LM5035B www.ti.com SNVS613C – JULY 2009 – REVISED APRIL 2013 Absolute Maximum Ratings (1) (2) VIN to GND -0.3V to 105V HS to GND -1V to 105V HB to GND -0.3V to 118V HB to HS -0.3V to 18V VCC to GND -0.3V to 16V RT, DLY to GND -0.3V to 5.5V COMP Input Current 10mA CS 1.0V All other inputs to GND -0.3V to 7V ESD Rating(3) Human Body Model 2kV Storage Temperature Range -65°C to 150°C Junction Temperature 150°C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. 2kV for all pins. The HB, HO, and HS pins are rated for 150V, machine model. Operating Ratings (1) VIN Voltage 13V to 105V External Voltage Applied to VCC 8V to 15V Operating Junction Temperature -40°C to +125°C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics. Electrical Characteristics Specifications with standard typeface are for TJ = 25°C, and those with boldface type apply over full Operating Junction Temperature range. VVIN = 48V, VVCC = 10V externally applied, RRT = 15.0 kΩ, RDLY = 27.4kΩ, VUVLO = 3V, VOVP = 0V unless otherwise stated (1) (2).

All electrical characteristics having room temperature limits are tested during production with TA = 25°C. All hot and cold limits are specified by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
