The LX1910 PWM buck regulator
achieves very high efficiencies over a
broad range of operating load
conditions. The LX1910 implements
a load-detection architecture and
enters a power-saving PFM mode
when driving small load currents
ensuring optimal regulator efficiency
over the entire output current range
thus maximizing battery life.
The
PWM
implements a fixed frequency of
1MHz (typ), the transconductance
error amplifier has 12μA of drive
with an output voltage swing rail to
rail. Compensation is external for
maximum user flexibility.

operating
mode
The LX1910 does not require a
minimum load current for stable
operation. There is no Under Voltage
Lockout
for
the
operational range includes 4V to 6V.
The regulator is capable of providing
an output dc load current of 850mA.
The SHDN pin places the device in a
sleep-mode drawing less than 1
μ
A of
quiescent current.
The LX1910 comes in space-saving
MSOP package allowing a complete
application circuit to occupy a very
small PCB area. These features make
