The LTC3406 is a high efficiency synchronous buck regulator that uses a constant frequency, current mode architecture. The supply current during operation is only 20µA and drops to ≤1µA in shutdown. The input voltage range is 2.5V to 5.5V and the output current is 600mA.
The LTC3406 is a monolithic synchronous step-down regulator using constant frequency, current mode architecture. It features an internal synchronous switch that eliminates the need for an external Schottky diode and supports output voltages as low as 0.6V. The device operates at a fixed 1.5MHz switching frequency to allow the use of small surface mount components.
