Minimum and maximum limits are ensured through test, design or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated, the following conditions apply: VIN = 24 V. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT POWER STAGE CHARACTERISTICS HS RDS-ON High-side MOSFET on-resistance 220 mΩ LS RDS-ON Low-side MOSFET on-resistance 200 mΩ tON-MIN Minimum high-side on-time IOUT = 500 mA 50 80 ns tOFF-MIN Minimum high-side off-time IOUT = 500 mA, ADJ 62 100 ns DMAX Maximum switch duty cycle 5-V and 3.3-V fixed output options 93% ADJ option 91% While in frequency foldback 97% L Integrated inductor - inductance 10 µH LDCR Integrated inductor - DCR 390 mΩ ENABLE VEN Enable input threshold voltage Rising 1.7 1.92 V VEN_HYST Enable input threshold hysteresis 0.42 0.52 V VEN_WAKE Enable input wake-up threshold 0.4 V IEN Enable pin input current VIN = VEN = 12 V 2.7 µA VCC REGULATOR VCC Internal VCC voltage VIN = 12 V, VOUT < 3.3 V 3.05 V VIN = 12 V, VOUT ≥ 3.3V 3.15 VCC_UVLO Internal VCC voltage input UVLO VIN rising 2.23 2.73 3.25 V VCC_UVLO_HYST Internal VCC voltage input UVLO hysteresis Hysteresis below VCC_UVLO 150 240 mV SOFT START tSS Soft-start time Time for VREF to ramp from 0% to 90% 1.8 3.5 5.5 ms tEN_LV Turnon delay with low VIN VIN < 4.2 V 4 ms tEN Turnon delay VIN = 12 V 0.7 ms tW Short circuit wait time (hiccup time) 8.0 ms THERMAL PROTECTION TSD Thermal shutdown Rising threshold 155 °C TSD_HYST Thermal shutdown hysteresis 15 °C |
