MP9842

36V, 2A, Low I_Q,

Step-Down Converter

DESCRIPTION

FEATURES

The MP9842 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter

with built-in power MOSFETs. It offers a very

compact solution that achieves 2A of

continuous output current with excellent load

and line regulation over a wide 3.3V to 36V

input supply range. The switching frequency is

programmable or can be synchronized to an

external clock in the range of 350kHz to

2.5MHz. Synchronous operation and ultra-low

14μA sleep mode quiescent current provide

high efficiency over the output current load

range, allowing the MP9842 to be used in a

variety of step-down applications in automotive

input environments and battery-powered

applications.

APPLICATIONS

•

Automotive Systems

Industrial Power Systems

Peak-current-mode operation provides fast

transient response and eases loop stabilization.

The excellent low dropout performance allows

the MP9842 to be used in high duty cycle

applications.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS

directive. For MPS green status, please visit the MPS website under

Quality Assurance. “MPS” and “The Future of Analog IC Technology” are

registered trademarks of Monolithic Power Systems, Inc.

Full protection features include over-current

protection (OCP), short-circuit protection (SCP),

and thermal shutdown. An open-drain power

good (PG) signal indicates when the output is

within 10% of its nominal voltage.

The MP9842 is available in a space-saving

QFN-16 (3mmx4mm) package.
