MP1498

High-Efficiency, 2A, 16V, 1.4MHz

Synchronous, Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP1498 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter

with built-in internal power MOSFETs. It offers a

very compact solution to achieve 2A continuous

output current with excellent load and line

regulation over a wide input supply range. The

MP1498 has synchronous mode operation for

higher efficiency over the output current load

range.



Wide 4.5V-to-16V Operating Input Range

100mΩ/40mΩ Low R_DS(ON)Internal Power

MOSFETs

Proprietary Switching-Loss–Reduction

Technique

High-Efficiency Synchronous Mode

Operation

Fixed 1.4MHz Switching Frequency

Can Synchronize to a 300kHz-to-3MHz

External Clock



Current-mode operation provides

fast



Externally-Programmable Soft-Start

OCP and Hiccup

Thermal Shutdown

Output Adjustable from 0.8V

Available in an 8-pin TSOT-23 Package

transient response and eases loop stabilization.

Protective features include over-current

protection, thermal shutdown, and external SS

control.

The MP1498 requires a minimal number of

readily-available external components and is

available in a space-saving 8-pin TSOT23

package.
