4 / 36 page LM25116 SNVS509C – APRIL 2007 – REVISED AUGUST 2011 www.ti.com 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. Absolute Maximum Ratings (1) VIN to GND -0.3V to 45V VCC, VCCX, UVLO to GND(2) -0.3 to 16V SW, CS to GND -3.0 to 45V HB to SW -0.3 to 16V HO to SW -0.3 to HB+0.3V VOUT to GND -0.3 to 45V CSG to GND -1V to 1V LO to GND -0.3 to VCC+0.3V SS to GND -0.3 to 7V FB to GND -0.3 to 7V DEMB to GND -0.3 to VCC RT to GND -0.3 to 7V EN to GND -0.3 to 45V ESD Rating, HBM(3) 2 kV Storage Temperature Range -55°C to +150°C Junction Temperature +150°C (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of the device is specified. Operating Ratings do not imply specified performance limits. For specified performance limits and associated test conditions, see the Electrical Characteristics tables. (2) These pins must not exceed VIN. (3) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. LO, HO and HB are rated at 1kV. 2kV rating for all pins except VIN which is rated for 1.5kV. Operating Ratings (1) (2) VIN 6V to 42V VCC, VCCX 4.75V to 15V HB to SW 4.75V to 15V DEMB to GND -0.3V to 2V Junction Temperature -40°C to +125°C (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of the device is specified. Operating Ratings do not imply specified performance limits. For specified performance limits and associated test conditions, see the Electrical Characteristics tables. (2) Note: RAMP, COMP are output pins. As such they are not specified to have an external voltage applied. Electrical Characteristics Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature range of -40°C to +125°C and are provided for reference only. Unless otherwise specified, the following conditions apply: VIN = 24V, VCC = 7.4V, VCCX = 0V, EN = 5V, RT = 16 kΩ, no load on LO and HO.
