MP9161A

2A, 6V, 1.5MHz, 17μA I_Q, COT

Synchronous Step-Down Converter

in 8-pin TSOT23

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP9161A is a monolithic, step-down,

switch-mode converter with built-in internal

power MOSFETs. It achieves a 2A continuous

output current from a 2.5V to 6V input voltage

range with excellent load and line regulation.

The output voltage is regulated as low as 0.6V.



Very Low I_Q: 17μA

Default 1.5MHz Switching Frequency

1.5% V_FBAccuracy

EN and Power Good for Power Sequencing

Wide 2.5V to 6V Operating Input Range

Output Adjustable from 0.6V

Up to 2A Output Current

100% Duty Cycle in Dropout

110mΩ and 60mΩ Internal Power MOSFET

Switches

The constant-on-time (COT) control scheme

provides fast transient response and eases loop

stabilization. Fault condition protection includes

cycle-by-cycle current limiting and thermal

shutdown.



Cycle-by-Cycle Over-Current Protection

Short-Circuit Protection with Hiccup Mode

Stable with Low ESR Output Ceramic

Capacitors

The MP9161A is available in a small TSOT23-8

package and requires a minimum number of

readily



Available in a TSOT23-8 Package

components.

The MP9161A is ideal for a wide range of

applications including high performance DSPs,

FPGAs, PDAs, and portable instruments.

APPLICATIONS
