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:
1. θ JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. All voltages are with respect to GND.
Electrical Specifications
Recommended operating conditions unless otherwise noted. Refer to “Functional Block Diagram” on page 2
and “Typical Application - High Voltage Input Primary Side Control ZVS Full-Bridge Converter” on page 3 and
“Typical Application - High Voltage Input Secondary Side Control ZVS Full-Bridge Converter” on page 4.
9V < VDD < 20V, RTD = 10.0k Ω , CT = 470pF, T A = -40°C to +105°C, Typical values are at T A = +25°C;
Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature
limits established by characterization and are not production tested.
