AOZ6763DI Absolute Maximum Ratings
(1)
Maximum Operating Ratings
(3) Exceeding the Absolute Maximum Ratings may damage the The device is not guaranteed to operate beyond the device. Maximum Operating ratings.
Parameter Rating Parameter Rating
Supply Voltage (VIN), EN (VEN) 20V Supply Voltage (VIN) 4.5V to 18V LX to GND -0.3V to VIN+0.3V Output Voltage Range 0.6V to 0.65*VIN LX to GND (20ns) -5V to 22V Ambient Temperature (TA) -40°C to +85°C VCC, FB to GND -0.3V to 6V Package Thermal Resistance 50°C/W VBST TO LX 6V DFN 3x3 (θJA)(4)
Notes:
Junction Temperature (TJ) +150°C 3. The device is not guaranteed to operate beyond the Maximum Storage Temperature (TS) -65°C to +150°C Operating ratings. ESD Rating(2) 2kV 4. The value of θJA is measured with the device mounted on a 1-in2
Notes:
FR-4 four layer board with 2oz copper and Vias, in a still air environ- ment with T 1. Exceeding the Absolute Maximum ratings may damage the device. A = 25°C. The value in any given application depends on the user’s specification board design. 2. Devices are inherently ESD sensitive, handling precautions are required. Human body model rating: 1.5k in series with 100pF.
Electrical Characteristics
TA = 25°C, VIN = VEN = 12V, VOUT = 3.3V, unless otherwise specified. Specifications in bold indicate an ambient temperature range of -40°C to +85°C. These specifications are guaranteed by design.
