10.5-A 12V-Input Dual Output
Integrated Switching Regulator
PT6982 Typical Characteristics
Efficiency vs Io1 (See Note A)
Vo1 Output Ripple vs Io1 (See Note A)
Power Dissipation vs Io1 (See Note A)
Safe Operating Area, Vin =12V (See Note B)
Note A:
Characteristic data has been developed from actual products tested at 25°C. This data is considered typical data for the Converter.
Note B:
SOA curves represent the conditions at which internal components are at or below the manufacturer’s maximum operating temperatures

Notes:
(i)
Io1(min) current of 0.1A can be divided between both outputs, Vo1 or Vo2. The module will operate at no load with reduced specifications.
(ii) The typical current is that which can be drawn simultaneously from both outputs under the stated operating conditions.
(iii) The sum of Io1 and Io2 must be less than Io1max, and Io2 must be less than Io2max.
