Typical Characteristics
PT4687 (Vo1/Vo2 =5V/1.8V); Vin =24V
Note A:
All Characteristic data in the above graphs has been developed from actual products tested at 25°C. This data is considered typical data for the converter.
Note B:
SOA curves represent operating conditions at which internal components are at or below manufacturer’s maximum rated operating temperatures.
