This Technical Specification states the minimum requirements for DC power supply for notebook computers. Specifically, it gives
– an electrical specification (performance characteristics),
– an ID pin method,
– a connector for DC power output. The no-load power and power efficiency are outside the scope of this Technical Specification.
Note that safety requirements are covered by IEC 60950-1 and EMC requirements are covered by CISPR 22 and CISPR 24. CISPR 32 may be used in place of CISPR 22 for this purpose. These requirements are neither re-stated nor challenged by this Technical Specification but the designer should give due consideration to the performance of the power supply when used with a compatible notebook computer.
NOTE Applications for use in aerospace, military, medical, or smart grid are not addressed in this Technical Specification.
