MP2141Q

1.5A, Synchronous Step-Down Converter

with VSEL Pin

DESCRIPTION

FEATURES

The MP2141Q is a monolithic, step-down,

switch-mode converter with built-in, internal

power MOSFETs. The MP2141Q achieves

1.5A of continuous output currents from a 2.3V

to 5.5V input voltage with excellent load and

line regulation.



PFM Quiescent Current: 20μA

EN for Power Sequencing

VSEL for PFM/PWM

Wide 2.3V to 5.5V Operating Input Range

Fixed Output Voltage: 0.61V/1.8V

Up to 1.5A of Output Current

120mΩ and 80mΩ Internal Power MOSFET

Switches

Output Discharging

Short-Circuit Protection (SCP) with Hiccup

Mode

Stable with Low ESR Output Ceramic

Capacitors

100% Duty Cycle

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 MP2141Q is ideal for a wide range of

applications including high performance DSPs,

wireless power, portable and mobile devices,

and other low-power systems.



Available in a SOT563 Package

The MP2141Q requires a minimal number of

APPLICATIONS

readily

available,

standard,

external

components and is available in an ultra-small

SOT563 package.



DDR/Codec
