Eutech Microelectronics EUP3020
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.| Part No. | EUP3020 |
