7 Specifications

7.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
Voltage at VIN, EN, PG to GND(2) −0.3 7 V
Voltage at OUT, FB to GND −0.3 3.6 V
Voltage at C1F+, C1F−, C2F+, C2F− to GND −0.3 7 V
Output current at OUT 300 mA
TJ Maximum junction temperature 150 °C
Tstg Storage temperature −55 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The voltage at EN, and PG can exceed VIN up to the maximum rated voltage without increasing the leakage current drawn by these mode select inputs.

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±500
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

7.3 Recommended Operating Conditions
