(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Should not exceed 7 V.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM) ±2000 V
Charged-device model (CDM) ±500

PARAMETER CONDITIONS MIN MAX UNIT
VDD Driver supply voltage 4.5 5.5 V
VIN Input supply voltage(1) 4.5 16 V
VOUT Output voltage 5.5 V
PWM PWM to PGND VDD + 0.3 V
IOUT Continuous output current VIN = 12 V, VDD = 5 V, VOUT = 1.2 V,
ƒSW = 500 kHz(2)		 60 A
IOUT-PK Peak output current(3) 90 A
ƒSW Switching frequency CBST = 0.1 µF (min), VOUT = 2.5 V (max) 1250 kHz
On-time duty cycle ƒSW = 1 MHz 85%

(1) Operating at high VIN can create excessive AC voltage overshoots on the switch node (VSW) during MOSFET switching transients. For reliable operation, the switch node (VSW) to ground voltage must remain at or below the Absolute Maximum Ratings.
(2) Measurement made with six 10-µF (TDK C3216X7R1C106KT or equivalent) ceramic capacitors across VIN to PGND pins.
(3) System conditions as defined in Note 2. Peak output current is applied for tp = 50 µs.
