ISL70001SEH, ISL70001SRH

Radiation Hardened and SEE Hardened 6A Synchronous Buck Regulator

FN7956

Rev 3.02

Sep 16, 2022

The ISL70001SEH, ISL70001SRH are radiation hardened and

Features

SEE hardened high efficiency monolithic synchronous buck

• ±1% reference voltage over line, load, temperature and

radiation

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.

• Current mode control for excellent dynamic response

• Full Mil-temp range operation (T = -55°C to +125°C)

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

• High efficiency >90%

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.

• Fixed 1MHz operating frequency

• Available in a thermally enhanced heatsink package - R48.B

• Operates from 3V to 5.5V supply

• Adjustable output voltage

- Two external resistors set V

from 0.8V to ~85% of V

OUT

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.

• Bidirectional SYNC pin allows two devices to be

synchronized 180° out-of-phase

• Starts into prebiased load

• Power-good output voltage monitor

• Adjustable analog soft-start

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’.

• Input undervoltage, output undervoltage and output

overcurrent protection

• Electrically screened to DLA SMD 5962-09225

• QML qualified per MIL-PRF-38535 requirements

Applications

• FPGA, CPLD, DSP, CPU core or I/O voltages
