EUP3020 - Eutech Microelectronics

EUP3020 Dual High-Efficiency 1.5MHz 1A PWM Step-Down DC-DC Converter

The EUP3020 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 EUP3020 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supp.
