MP2162AGQH-P Datasheet, PDF (1/17 Pages) MPS Industries, Inc. – 2A, 6V, 1.5MHz, 17μA IQ, COT Synchronous Step-Down Converter

The Future of Analog IC Technology
DESCRIPTION
The MP2162A is a monolithic step-down,
switch-mode converter with built-in internal
power MOSFETs. It achieves 2A of 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 MP2162A is available in small QFN-8
(2.0x1.5mm), TQFN-8 (2.0x1.5mmx0.75mm)
and UTQFN-8 (2.0mmx1.5mmx0.55mm)
packages and requires only a minimal number
of readily available, standard, external
components.
The MP2162A is ideal for a wide range of
applications, including high performance DSPs,
FPGAs, PDAs, and portable instruments.
