EUP3419
Dual 1.
5MHz, 1A Synchronous Step-Down Converter
DESCRIPTION
The EUP3419 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 EUP3419 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery.
Each converter can supply 1A of load current from a 2.
5V to 5.
5V input voltage.
The output voltage can be regulated as low as 0.
6V.
The EUP3419 can also run at 100% duty cycle for low dropout applications.
25µA per channel quiescent current at light loads increases efficiency and battery life.
