MP2263

Wide Input 3.3V - 30V, 3A, 12µA I_Q,

Synchronous, Step-Down Converter with

External Soft Start and Power Good

in Small 2x3mm QFN Package

DESCRIPTION

FEATURES

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.



Wide 3.3V to 30V Operating Voltage Range

3A Continuous Output Current

1μA Low Shutdown Supply Current

12μA Sleep Mode Quiescent Current

90mΩ/38mΩ High-Side/Low-Side R_DS(ON)for

Internal Power MOSFETs

350kHz to 2.5MHz Programmable Switching

Frequency

Power Good Output

External Soft Start

80ns Minimum On Time

Selectable Forced PWM Mode and Auto

PFM/PWM Mode

Low Dropout Mode



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.



Hiccup Over-Current Protection (OCP)

Available in a QFN-15 (2mmx3mm)

Package

An open-drain power good signal indicates the

output.

APPLICATIONS



Battery-Powered Systems

Smart Homes

Wide Input Range Power Supplies

Standby Power Supplies

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.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS

directive. For MPS green status, please visit the MPS website under Quality

Assurance. “MPS” and “The Future of Analog IC Technology” are registered
