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
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 RDS(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.
