MP2158

1A, 6V, 1.5MHz, 17μA I_Q, COT

Synchronous Step Down Switcher

In Ultra-small 2x1.5mm QFN

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2158 is a monolithic step-down switch

mode converter with built-in internal power

MOSFETs. It achieves 1A continuous output

current from a 2.5V to 6V input voltage with

excellent load and line regulation. The output

voltage can be regulated as low as 0.6V.



Very Low I_Q: 17μA

Default 1.5MHz Switching Frequency

EN and Power Good for Power Sequencing

Ultra-small 2.0x1.5mm QFN8 Package

Wide 2.5V to 6V Operating Input Range

Output Adjustable from 0.6V



Up to 1A Output Current

118mΩ and 88mΩ Internal Power MOSFET

Switches

Cycle-by-Cycle Over Current Protection

Short Circuit Protect with Hiccup Mode

Stable with Low ESR Output Ceramic

Capacitors

The

Constant-On-Time

control

scheme

provides fast transient response and eases loop

stabilization. Fault condition protection includes

cycle-by-cycle current limiting and thermal

shutdown.



The MP2158 is available in the small QFN8

2.0x1.5mm package and requires a minimum

number of readily available standard external

components.

APPLICATIONS



Wireless/Networking Cards

Portable Instruments

Battery Powered Devices

Low Voltage I/O System Power

The MP2158 is ideal for a wide range of

applications including High Performance DSPs,

FPGAs, PDAs, and portable instruments.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Products, Quality Assurance page.
