6.3 Recommended Operating Conditions

TA = 25°C (unless otherwise noted)
MIN MAX UNIT
VDD Gate drive voltage 4.5 5.5 V
VIN Input supply voltage (1) 16 V
IOUT Continuous output current VIN = 12 V, VDD = 5 V, VOUT = 1.8 V,
ƒSW = 500 kHz, LOUT = 0.29 µH(3) 		35 A
IOUT-PK Peak output current(3)(2) 70 A
ƒSW Switching frequency CBST = 0.1 µF (min) 2000 kHz
On-time duty cycle 85%
Minimum PWM On-time 40 ns
Operating temperature –40 125 °C
(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 C3216X5R1C106KT or equivalent) ceramic capacitors placed across VIN to PGND pins.
(3) Peak output current is applied for tp = 10 ms, duty cycle ≤ 1%.
