hronous current mode step-down dc-dc converter, capable of delivering 2A load current with excellent line and load regulation. Operating with an input voltage range between 2.7V and 5.5V, the device is ideal for portable applications powered by a single Li-Ion battery cell or by 3-cell NiMH/NiCd batteries. The EUP3420 operates at 1.5MHz fixed frequency PWM mode and provides very low output ripple voltage for noise sensitive applications. The internal integrated synchronous switch increases efficiency while eliminates the need for an external Schottky diode. The EUP3420 is available in the 10-pin MSOP and 10-pin TDFN package.
