Design PC power systems that are space conscious and thermally efficient

PC and notebook designs require efficient power and battery management. With low quiescent currents, our load switches take only a minimal percentage of power budgets, while bringing necessary protection features to downstream systems. 

Benefits:

  • Protections such as inrush current control and short-circuit and reverse current protection.
  • A thermal shutdown feature to give a heat-conscious solution.
  • Small and compact packaging – less than 5 mm2.
