PIN DESCRIPTIONS (continued)
HTSSOP WQFN Name Description
Pin Pin
17 NC No electrical contact.
21 NC No electrical contact.
23 NC No electrical contact.
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 AGND -0.3 to 75V
SW to AGND -3.0 to 75V
HB to SW -0.3 to 15V
VCC to AGND
(2)
-0.3 to 15V
HO to SW -0.3 to HB+0.3V
LO to AGND -0.3 to VCC+0.3V
FB, DEMB, RES, VCCDIS, UVLO to AGND -0.3 to 15V
CM, COMP to AGND
(3)
-0.3 to 7V
SS, RAMP, RT to AGND -0.3 to 7V
CS, CSG, PGND, to AGND -0.3 to 0.3V
ESD Rating HBM
(4)
2kV
Storage Temperature -55°C to +150°C
Junction Temperature +150°C
(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur.
(2) See Application Information section when input supply voltage is less than the VCC voltage.
(3) These pins are output pins. As such they are not specified to have an external voltage applied.
(4) The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
Operating Ratings
(1)
VIN
(2)
5.5V to 65V
VCC 5.5V to 14V
HB to SW 5.5V to 14V
Junction Temperature -40°C to +125°C
(1) Operating Ratings are conditions under which operation of the device is intended to be functional, but does not ensure specific
performance limits. For specifications and test conditions see Electrical Characteristics.
(2) Minimum VIN operating voltage is defined with VCC supplied by the internal HV startup regulator and no external load on VCC. When
VCC is supplied by an external source, minimum VIN operating voltage is 4.5V.
