MPM3804
0.6A, 5.5V Input Step-Down Module
Synchronous Regulator with Integrated Inductor
in Ultra-Small 2x2x0.9mm QFN Package
DESCRIPTION
FEATURES
The MPM3804 is a monolithic, step-down,
switch-mode converter with built-in, internal
power MOSFETs and an inductor. The
MPM3804 achieves 0.6A of continuous output
current from a 2.3V to 5.5V input voltage range
with excellent load and line regulation. The
output voltage can be regulated as low as 0.6V.
Only input capacitors, output capacitors, and
feedback (FB) resistors are required to
complete the design.
Up to 91% Peak Efficiency
Low IQ: 11μA
Wide 2.3V to 5.5V Operating Input Range
Output Voltage as Low as 0.6V
100% Duty Cycle in Dropout
0.6A Output Current
120mΩ and 80mΩ Internal Power
MOSFETs
2.4MHz Frequency
EN and Power Good for Power Sequencing
Cycle-by-Cycle Over-Current Protection
(OCP)
0.5ms Internal Soft-Start Time
Output Discharge
Short-Circuit Protection (SCP) with Hiccup
Mode
Thermal Shutdown
The constant-on-time (COT) control scheme
provides a fast transient response, high
light•load efficiency, and easy loop stabilization.
Full protection features include cycle•by•cycle
current limiting and thermal shutdown.
The MPM3804 is ideal for a wide range of
applications, including high-performance DSPs,
wireless power, portable and mobile devices,
and other low-power systems.
