CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
4. _JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379.
5. For _JC, the “case temp” location is the center of the exposed metal pad on the package underside.
6. Unless otherwise noted, all voltages provided in this specification refer to GND.
7. Maximum Operation Voltage includes DC operation voltage level and transient peak noise level.
Electrical Specifications Refer to the Block Diagram (page 11) and Typical Application Schematics (page 13). Operating conditions
unless otherwise noted: V_VIN = 48V, V_V6 = 6V, V_V12 = 12V, V_BAT12 = 12V, V_PVCC = 5.2V, V_VCC = 5.2V, V_EN = 5.0V, and T_A = -40°C to +125°C. Typicals are
at T_A = +25°C. Boldface limits apply across the operating temperature range, -40°C to +125°C.
