Miniature switching regulators

The 3-MHz 600-mA dc-to-dc converter balances low operating input voltage capability, low quiescent current and small size offering designers more flexibility in meeting strict system power and PCB area budgets without increasing battery capacity.

ADP2108 dc-to-dc converter
The 3 MHz 600-mA ADP2108 dc-to-dc converter balances low operating input voltage capability, low quiescent current and small size offering designers more flexibility in meeting strict system power and PCB area budgets without increasing battery capacity. The converter operates from an input voltage as low as 2.3 V to provide excellent conversion efficiency, transient response and protection. This low operating voltage allows designers to fully use the available battery energy for 2.5-V and 3-V power loads before recharging, which can eliminate the requirement of a more expensive buck-boost regulator in some applications. During light load conditions, the converter switches to a low-quiescent power-save mode for additional battery life savings.
