Dual 1.5MHz, 600mA Synchronous Step-Down Converter
Features
General Description
Applications
TV Tuner/Box
Portable Instrument
The APW7134 contains two independent 1.5MHz con-
stant 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 APW7134 is ideal for
powering portable equipment that runs from a single
cell Lithium-Ion (Li+) battery. Each converter can sup-
ply 600mA of load current from a 2.5V to 5.5V input
voltage. The output voltage can be regulated as low as
0.6V. The APW7134 can also run at 100% duty cycle
for low dropout applications.
