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.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/
JA
. Exceeding the maximum allowable powe
r
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
