3 / 48 page LM2597, LM2597HV www.ti.com SNVS119C – MARCH 1998 – REVISED APRIL 2013 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

Operating Ratings indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For 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) VIN = 40V for the LM2597 and 60V for the LM2597HV. (4) Voltage internally clamped. If clamp voltage is exceeded, limit current to a maximum of 1 mA. (5) The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin.
