The LT8609 family of step-down (buck) regulators from Linear Technology, now a part of ADI, can provide 2 A of continuous current with peak loads of 3 A of current. With a wide voltage input range from 3 V to 24 V or 42 V, the LT8609 consumes a very low 1.7 μA of non-switching quiescent current. This buck regulator is adjustable and synchronizable with a frequency range of 200 kHz to 2.2 MHz. The LT8609 is available in three types, with the standard having a fast switching edge speed, and can operate in both pulse-skipping mode and burst mode. The LT8609A has slower switch edges for lower EMI emissions. The LT8609B operates in pulse-skipping mode only and fast-switch edge speed. The LT8609 is ideal for GSM transceivers, low EMI requirements, and general purpose step-down applications.
