DATASHEET

ISL70002SEH, ISL73002SEH

Radiation Hardened and SEE Hardened 22A Synchronous Buck Regulators with

Current Sharing

FN8264

Rev.12.01

Mar 31, 2022

The ISL70002SEH and ISL73002SEH (ISL7x002SEH) are

Features

radiation hardened and SEE hardened high-efficiency

• DLA SMD 5962-12202

• Maximum output current (“Single Phase”):

- 22A with external Schottky (T ≤125°C, PVIN ≤5.5V)

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

capability is primarily determined by PVIN voltage with up to

- 18A (T ≤125°C, PVIN ≤5.5V)

- 14A (T ≤125°C, PVIN ≤6.2V)

- 12A (T ≤150°C, PVIN ≤6.2V)

22A for a single IC at PVIN ≤ 5.5V for T ≤ +125°C. Two

ISL7x002SEH devices, configured to current share, can

• Maximum output current (“Dual Phase”)

- 38A (27% worst case current sharing)

• 1MHz or 500kHz switching frequency

provide up to 38A of total output current at PVIN ≤ 5.5V for T

≤ +125°C assuming ±27% worst-case current share

accuracy.

• 3V to 6.2V supply voltage range

The devices use peak current-mode control with integrated

error amp compensation and pin-selectable slope

• ±1% reference voltage (line, load, temperature, and rad)

compensation. Switching frequency is also pin selectable to

either 1MHz or 500kHz. Two devices can be synchronized

180° out-of-phase to reduce input RMS ripple current.

• Redundancy/junction isolation: exceptional SET

performance

• Excellent transient response

High integration makes them an ideal choice to power 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.

• High efficiency >90%

• Two ISL7x002SEH synchronization, inverted-phase

• Comparator input for enable and power-good

• Input undervoltage, output undervoltage, and adjustable

output overcurrent protection

The ISL7x002SEH is available in a thermally enhanced heat

spreader package (R64.C)

• QML qualified per MIL-PRF-38535

• Full military temperature range operation (-55°C to

+125°C)

Applications

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

• Radiation environment - ISL70002SEH

- HDR (50-300rad(Si)/s): 100krad(Si)

- LDR (0.01rad(Si)/s): 50krad(Si)

• Low-voltage, high-density distributed power systems

• Radiation environment - ISL73002SEH

- LDR (0.01rad(Si)/s): 50krad(Si).

• SEE hardness (See the SEE Test report for details)
