DESCRIPTION
The LTM?8080 is a 40VIN, dual 500mA or single 1A
ultralow noise, ultrahigh PSRR μModule? regulator.
LTM8080 has cascaded architecture which contains a
40VIN step-down Silent Switcher regulator with an integrated
EMI noise shield followed by dual high-performance
low dropout linear regulators. The dual LDOs feature
ADI’s ultralow noise and ultrahigh PSRR architecture
for powering noise-sensitive applications. The LTM8080
is an integrated solution comprised of a switcher and
LDOs, which offers both advantages while maintaining a
small size and significantly reduced PCB layout sensitivity.
The package includes the controllers, power switches,
inductors, and support components. In addition, the
LTM8080 has a built-in voltage tracking function that
automatically sets VBUS to either 2.5V nominal or 1V
higher than VOUT1, whichever is greater, to achieve superior
noise performance and minimize power dissipation.
The LTM8080 is packaged in a thermally enhanced,
compact (9mm × 6.25mm × 3.32mm) over-molded
Ball Grid Array (BGA) package suitable for automated
assembly by standard surface mount equipment and is RoHS compliant.
