MPQ2123
6V, 2A, Configurable Frequency,
Synchronous Buck Converter,
AEC-Q100 Qualified
DESCRIPTION
FEATURES
The MPQ2123 is a configurable frequency
(300kHz to 2.2MHz), synchronous step-down
converter. It can achieve up to 2A of continuous
output current with peak current control for
excellent transient response and efficiency. It
operates from a 2.7V to 6V input voltage range,
and can generate an output voltage as low as
0.606V. The MPQ2123 is ideal for a wide range
2.7V to 6V Operating Input Range
Adjustable Output from 0.606V
Up to 2A Continuous Output Current
High-Efficiency Synchronous Mode Control
40mΩ and 30mΩ Internal Power MOSFETs
Up to 2.2MHz Configurable Frequency
Up to 2.2MHz External Sync Clock
45μA Quiescent Current (IQ)
Low Shutdown Current (ISD)

Package
The MPQ2123 integrates a 40mΩ high-side
MOSFET (HS-FET) and a 30mΩ synchronous
rectifier for high efficiency without an external
Schottky diode. The MPQ2123 can be
configured
to
operate
in
advanced
asynchronous modulation (AAM) mode or forced
continuous conduction mode (FCCM) under
light-load conditions. AAM provides high
efficiency by reducing switching losses at light
load, while FCCM offers controllable frequency
and a lower output ripple.
The MPQ2123 features soft start (SS), an
external sync clock, enable (EN) control, and a
power good (PG) indicator.
Available in AEC-Q100 Grade 1
Full protection features include over-current
protection (OCP) with valley current detection to
avoid current runaway, short-circuit protection
(SCP), input under-voltage lockout (UVLO),
output over-voltage protection (OVP), and
thermal shutdown.
APPLICATIONS
Automotive Infotainment Systems
Automotive Clusters
Automotive Telematics
Industrial Supplies
With internal compensation, the MPQ2123
requires a minimal number of readily available,
standard external components. It is available in
a QFN-11 (2mmx3mm) package.
