Features: The Future of Analog IC Technology MP22 63 Wide Input 3.3V - 30V, 3A, 12µA IQ, Synchronous, Step-Down Converter with External Soft Start and Power Good in S mall 2x3mm QFN Package DESCRIPTION The MP2263 is a frequency-programmable (35 0kHz to 2.5MHz), synchronous, step-down , switching regulator with integrated, internal, high-side and low-side power MOSFETs. The MP2263 provides 3A of high ly efficient output current with curren t-mode control for fast loop response. The wide 3.3V-to-30V input range accomm odates a variety of step-down applicati ons. A 1μA shutdown mode quiescent cur rent allows the MP2263 to be used in ba ttery-powered applications. High power conversion efficiency over a wide load range is achieved by scaling down the s witching frequency at light-load condit ion to reduce switching and gate drivin g losses. An open-drain power good sign al indicates the output. Frequency fold back helps prevent inductor current run away during start-up. Thermal shutdown provides reliable and faul.

The Future of Analog IC Technology
MP2263
Wide Input 3.3V - 30V, 3A, 12µA IQ,
Synchronous, Step-Down Converter with
External Soft Start and Power Good
in Small 2x3mm QFN Package
DESCRIPTION
The MP2263 is a frequency-programmable
(350kHz to 2.5MHz), synchronous, step-down,
switching regulator with integrated, internal,
high-side and low-side power MOSFETs. The
MP2263 provides 3A of highly efficient output
current with current-mode control for fast loop
response.
The wide 3.3V-to-30V input range accommodates
a variety of step-down applications. A 1μA
shutdown mode quiescent current allows the
MP2263 to be used in battery-powered
applications.
High power conversion efficiency over a wide
load range is achieved by scaling down the
switching frequency at light-load condition to
reduce switching and gate driving losses.
An open-drain power good signal indicates the
output.
Frequency foldback helps prevent inductor
current runaway during start-up. Thermal
shutdown provides reliable and fault-tolerant
operation. High-duty cycle and low drop-out
mode are provided for battery-powered systems.
The MP2263 is available in a QFN-15
(2mmx3mm) package.
