EUP3409 Dual 1.5MHz, 800mA Synchronous Step-Down Converter DESCRIPTION The EUP3409 contains two independent 1.5MHz constant frequency, current mode, PWM step-down converters. Each converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The EUP3409 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supply 800mA of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The EUP3409 can also run at 100% duty cycle for low dropout applications. Typical Application Circuit FEATURES z Up to 96% Efficiency z 1.5MHz Constant Switching Frequency z 800mA Load Current on Each Channel z 2.5V to 5.
