EUP3020
Dual High-Efficiency 1.5MHz 1A PWM
Step-Down DC-DC Converter
DESCRIPTION
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
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 EUP3020 can also run at 100% duty cycle
for low dropout applications.
EUP3020 is available in an adjustable output or fixed
output 1.2V, 1.8V and 3.3V.
