MP2162
DESCRIPTION
The MP2162 is a monolithic step-down switch
mode converter with built-in internal power
MOSFETs. It achieves 2A continuous output
current from a 2.5V to 6V input voltage with
excellent load and line regulation. The output
voltage can be regulated as low as 0.6V.
The
Constant-On-Time
control
scheme
provides fast transient response and eases loop
stabilization. Fault condition protection includes
cycle-by-cycle current limiting and thermal
shutdown.
The MP2162 is available in the small QFN8
2.0x1.5mm package and requires a minimum
number of readily available standard external
components.
The MP2162 is ideal for a wide range of
applications including High Performance DSPs,
FPGAs, PDAs, and portable instruments.
