MP2269

3.3V - 30V, 1A, 12µA I_Q,

Synchronous, Step-Down Converter

with External Soft Start and Power Good

in 2x3mm QFN Package

DESCRIPTION

FEATURES

The MP2269 is a frequency-programmable

(350kHz to 2.5MHz), synchronous, step-down,

switching regulator with integrated, internal,

high-side and low-side power MOSFETs. The

MP2269 provides 1A of highly efficient output

current with current-mode control for fast loop

response.



Wide 3.3V to 30V Operating Voltage Range

1A Continuous Output Current

1μA Low Shutdown Supply Current

12μA Sleep Mode Quiescent Current

180mΩ/80mΩ High-Side/Low-Side R_DS(ON)

for Internal Power MOSFETs

350kHz to 2.5MHz Programmable Switching

Frequency



The wide 3.3V to 30V input range



Power Good Output

External Soft Start

80ns Minimum On Time

Selectable Forced PWM Mode and Auto

PFM/PWM Mode

accommodates

variety of step-down

applications. A 1μA shutdown mode quiescent

current allows the MP2269 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.



Low Dropout Mode

Hiccup Over-Current Protection (OCP)

Available in a QFN-15 (2mmx3mm)

Package

An open-drain power good signal indicates the

output signal. 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.

APPLICATIONS
