ISL70001SEH, ISL70001SRH

Radiation Hardened and SEE Hardened 6A Synchronous Buck Regulator

DATASHEET

The ISL70001SEH, ISL70001SRH are radiation hardened and

SEE hardened high efficiency monolithic synchronous buck

regulators with integrated MOSFETs. This single chip power

solution operates over an input voltage range of 3V to 5.5V

and provides a tightly regulated output voltage that is

externally adjustable from 0.8V to ~85% of the input voltage.

Output load current capacity is 6A for TJ < +145°C.

High integration and class leading radiation tolerance makes

the ISL70001SEH, ISL70001SRH ideal choices to power

many of today’s small form factor applications. Two devices

can be synchronized to provide a complete power solution for

large scale digital ICs, like field programmable gate arrays

(FPGAs) that require separate core and I/O voltages.

In applications where the ENABLE input is tied high to PVIN we

recommend that the input voltage ramp rate be equal to or

greater than 10V/ms. This is to prevent unwanted voltage from

prematurely appearing on the output.

For a PVIN voltage that has a slower ramp rate or is stepped up

we recommend use of the ISL70001ASEH. Ensuring that the

ENABLE input is held low until the chosen VINPOR is satisfied

will prevent this ‘false start’.

Applications
