| EUP3291 ds3291 ver1.0 mar. 2013 1 1.5a, 2.25mhz synchronous step-down dc/dc regulator description the EUP3291 is synchronous step-down dc-dc converters optimized for battery powered portable applications. the 2.7v to 5.5v input voltage range makes EUP3291 ideal for powering portable equipment that runs from 1-cell li-ion or 3-cell nimh/nicd batteries. the device is also suitable to operate f rom a standard 3.3v or 5v voltage rail. the EUP3291 operates at 2.25mhz fixed switching frequency allowing the use of small inductors and capacitors to achieve a small solution size. the in ternal synchronous switch increases efficiency and elimina tes the need for an external schottky diode. the eup329 1 has internal soft start and avoids inrush current d uring startup. the EUP3291 has a user selectable mode of forced pwm and pfm/pwm mode. the forced pwm mode operation provides the lowest ripple noise and the pfm mode operation provides high efficiency at light lo ads. the EUP3291 is available in tdfn-6 package and it provides up to 1.5a output current. typical application circuit features high efficiency up to 95% 2.25mhz constant switching frequency 1.5a available load current 30a typical quiescent current 2.7v to 5.5v input voltage range adjustable output voltage as low as 0.6v no schottky diode required short circuit and thermal protection internal soft start function available in tdfn-6 package rohs compliant and 100% lead(pb)-free halogen-free applications ssd module smart phones tablet pc portable media players c/ p, fpga and dsp power plug-in dc/dc modules for routers and switchers figure 1.
