The CXSD62298 is a high efficiency synchronous,dual channel PWM step-down 

DC/DC converter working under an input voltage range of 2.5V to 5.5V. It integrates

 two PWM synchronous step-down DC-DC converters. 100% duty cycle capability 

extends battery life in portable devices,while the quiescent current (one channel) is 

200μA with no load, and drops to<1μA in shutdown.Each DC-DC converter has 

independent enable input and short-circuit protection allowing versatile power 

sequence combination.The CXSD62298 converters are available in the  industry 

standard DFN3*3-10L packages (or upon request).
