EUP3412 1.5A/1.5MHz, Synchronous Step-Down Converter with Soft Start DESCRIPTION The EUP3412 is a synchronous current mode step-down dc-dc converter, capable of driving 1.5A 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 EUP3412 operates at a fixed switching frequency of 1.5MHz and PWM operation 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 EUP3412 is available in the 10-pin MSOP and 10-pin TDFN package. FEATURES High Efficiency up to 96% 1.
