9A, 3.8V to 18V Input, Synchronous Buck Regulator

The ISL85009 is a highly efficient, monolithic, synchronous

buck regulator that can deliver 9A of continuous output current

from a 3.8V to 18V input supply. The device uses current mode

control architecture with a fast transient response and

excellent loop stability.

Features

• Power input voltage range variable 3.8V to 18V

• PWM output voltage adjustable from 0.6V

• Up to 9A output load

The ISL85009 integrates very low ON-resistance high-side and

low-side FETs to maximize efficiency and minimize external

component count. The minimum BOM and easy layout

footprint are extremely friendly to space constraint systems.

• Prebias start-up, fixed 3ms soft-start

• Selectable f

of 300kHz, 600kHz, and external

synchronization up to 1MHz

• Peak current mode control

- DCM/CCM

The operation frequency of this device can be set using the

FREQ pin: 600kHz (FREQ = float) and 300kHz (FREQ = GND).

The device can also be synchronized to an external clock up to

1MHz.

- Thermally compensated current limit

- Internal/external compensation

Both high-side and low-side MOSFET current limit along with

reverse current limit, fully protect the regulator in an

overcurrent event. Selectable OCP schemes can fit various

applications. Other protections, such as input/output

overvoltage and over-temperature, are also integrated into the

device which give required system level safety in the event of

fault conditions.

• Open-drain PG window comparator

• Output overvoltage and thermal protection

• Input overvoltage protection

• Integrated boot diode with undervoltage detection

• Selectable OCP schemes

- Hiccup OCP

The ISL85009 is offered in a space saving 15 Ld 3.5mmx3.5mm

Pb-free TQFN package with great thermal performance and

0.8mm maximum height.

- Latch-off

• Compact size 3.5mmx3.5mm, 15 Ld TQFN

Applications

• Servers and cloud infrastructure POLs

• IPCs, factory automation, and PLCs

• Telecom and networking systems

• Storage systems

• Test measurement
