PJ3406 Description
The  PJ3406 is high  efficiency synchronous, step-down DC/DC converters working under an input voltage range of 2.5V to 5.5V. This feature  makes the  PJ3406 suitable for single  Li-lon battery-powered applications. 100% duty cycle capability extends battery life in portable devices, while the quiescent current is 230µA with no load, and drops to < 1µA in shutdown.The internal synchronous 0.35Ω, 1A switch is desired to increase efficiency without an external Schottky diode. The 1.5 MH·fixed switching frequency allows the
using of tiny, low profile inductors and ceramic capacitors, which minimized overall solution footprint. The  PJ3406 regulators are available in the industry standard SOT-23-5 power packages (or upon request).
