Features: MP21600 0.6A, Synchronous, Step-Down Con verter with 11µA IQ in Ultra-Small 1x1 .5mm QFN DESCRIPTION The MP21600 is a monolithic, step-down, switch-mode conv erter with built-in, internal power MOS FETs. The MP21600 achieves 0.6A of cont inuous output current from a 2.3V to 5. 5V input voltage range with excellent l oad and line regulation. The output vol tage can be regulated as low as 0.6V. T he constant-on-time (COT) control schem e provides fast transient response and eases loop stabilization. Fault protect ions include cycle-bycycle current limi ting and thermal shutdown. The MP21600 is ideal for a wide range of applicatio ns, including high-performance DSPs, wi reless power, portable and mobile devic es, and other low-power systems. The MP 21600 requires a minimal number of read ily available, standard, external compo nents is available in an ultra-small QF N6 (1.0mmx1.5mm) package. FEATURES  Low IQ: 11μA  2.4MHz Switching Fre quency  Enable (EN) Pin for Power Sequencing  Wide 2.3V to 5.5V Ope.

MP21600
0.6A, Synchronous, Step-Down Converter
with 11µA IQ in Ultra-Small 1x1.5mm QFN
DESCRIPTION
The MP21600 is a monolithic, step-down,
switch-mode converter with built-in, internal
power MOSFETs. The MP21600 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.
The constant-on-time (COT) control scheme
provides fast transient response and eases loop
stabilization. Fault protections include cycle-by-
cycle current limiting and thermal shutdown.
The MP21600 is ideal for a wide range of
applications, including high-performance DSPs,
wireless power, portable and mobile devices,
and other low-power systems.
The MP21600 requires a minimal number of
readily available, standard, external
components is available in an ultra-small QFN-
6 (1.0mmx1.5mm) package.
