General Description
The ET3406 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current
mode architecture. The device is available in an adjustable version and fixed output voltages of 1.5V and 1.8V. Supply
current drops to ≤1μA in shutdown. The 2.5V to 5.5V input voltage range makes the ET3406 ideally suited for single LiIon
batterypowered applications. 100% duty cycle provides low dropout operation, extending battery life in portable
systems.
Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The
internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output
voltages are easily supported with the 0.6V feedback reference voltage.
