General Description
LN3492 is a fully integrated, high– efficiency 2A
synchronous rectified step-down converter. The LN3492
operates at high efficiency over a wide output current load
range.
This device offers two operation modes, PWM control
and PFM Mode switching control, which allows a high
efficiency over the wider range of the load.
The LN3492 requires a minimum number of readily
available standard external components and is available in
an 6-pin SOT23 ROHS compliant package.
