6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
Supply voltages on pin VIN (2) –0.3 7 V
Voltages on pins EN, FB (2) –0.3 VIN + 0.3 V
Switch voltage on pin SW (2) 30 30 V
Operating junction temperature, TJ –40 150 °C
Storage temperature, Tstg –65 150 °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) All voltage values are with respect to network ground terminal.

6.2 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) ±750
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. Pins listed as ±XXX V may actually have higher performance.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. Pins listed as ±YYY V may actually have higher performance.

6.3 Recommended Operating Conditions

MIN NOM MAX UNIT
VIN Input voltage range 1.8 6 V
VOUT Output voltage range 28 V
L Inductor(1) 2.2 10 μH
f Switching frequency(1) 1 MHz
CIN Input capacitor (1) 4.7 μF
COUT Output capacitor (1) 1 μF
TA Operating ambient temperature –40 85 °C
TJ Operating junction temperature –40 125 °C
