The ADP5310 combines dual buck regulators and one load switchin a 16-lead TSSOP_EP package that meets demanding performanceand board space requirements. The device enables directconnection to a wide input voltage range of 2.7 V to 15.0 V, allowingthe use of multiple alkaline/NiMH or lithium cells and otherpower sources.The buck regulator in Channel 1 uses a current mode, constantfrequency pulse-width modulation (PWM) control scheme forexcellent stability and transient performance, which provides upto 800 mA of output current. The automatic PWM/pulse skippingmode (PSM) control scheme achieves excellent efficiency in lightoutput current. A power-good signal indicates that the outputof Channel 1 is within 92% of its nominal value.An ultralow power buck regulator is integrated in Channel 2 withthe SYNC/MODE pin to control its operation mode. WhenSYNC/MODE is set to low, the buck regulator operates in hysteresismode, which draws only 700 nA of quiescent current to regulatethe output under zero load and provides up to 50 mA of outputcurrent. Hysteresis mode helps achieve excellent efficiency at lessthan 1 mW and can work as a keep-alive power supply in a batterypoweredsystem. When the SYNC/MODE pin is set to high, thebuck regulator switches to a traditional constant frequency PWMcontrol scheme to provide low output ripple for noise sensitive
