ISL78223 Datasheet, PDF (19/20 Pages) Intersil Corporation – ZVS Full-Bridge PWM Controller with Adjustable Synchronous Rectifier Control

ISL78223
Thermal Protection
Internal die over temperature protection is provided. An
integrated temperature sensor protects the device should the
junction temperature exceed +140°C. There is approximately
+15°C of hysteresis.
Ground Plane Requirements
Careful layout is essential for satisfactory operation of the device.
A good ground plane must be employed. V_DD and V_REF should be
bypassed directly to GND with good high frequency capacitance.
