The is alow EMI signature, asynchronous,

step-down, switch-mode converter with internal power

MOSFETs.

It offers a very compact solution to provide a 3A continuous current over a wide input supply range, with excellent load

and line regulation.achieves low EMI signature with well controlled switching edges. Fault condition

protection includes programmable-output over-voltage protection,Constant on time Mode, and thermal shutdown.3903

requires a minimal number of readily available standard external components. It is available in ESOP8

package.
