February 22, 2014 Radiation Hardened and SEE Hardened 6A Synchronous Buck Regulator
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 < +145В°C.
High integration and class leading radiation tolerance makes
the ISL70001SEH, ISL70001SRH ideal choices to power
many of todayвЂ™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 ...
