ISL8117

Synchronous Step-Down PWM Controller

The ISL8117 is a synchronous buck controller used to

generate POL voltage rails and bias voltage rails for a

wide variety of applications in industrial and general

purpose segments. Its wide input and output voltage

ranges make it suitable for telecommunication and

after-market automotive applications.

Features

• Wide input voltage range: 4.5V to 60V

• Wide output voltage range: 0.6V to 54V

• Light-load efficiency enhancement

○ Low ripple Diode Emulation mode with pulse

skipping

The ISL8117 uses the valley current modulation

technique to bring hassle-free power supply design

with a minimal number of components and complete

protection from unwanted events.

• Programmable soft-start

• Supports prebiased output with SR soft-start

• Programmable frequency: 100kHz to 2MHz

• External sync

The ISL8117 offers programmable soft-start and

enable functions along with a power-good indicator

for ease of supply rail sequencing and other

• PGOOD indicator

housekeeping requirements. In ideal situations, a

complete power supply circuit can be designed with

10 external components and provide OV/OC/OT

protections in a space conscious 16 Ld 4mmx4mm

QFN or easy to assemble 6.4mmx5mm 16 Ld

HTSSOP package. Both packages use an EPAD to

improve thermal dissipation and noise immunity. Low

pin count, fewer external components, and default

internal values makes the ISL8117 an ideal solution

for quick to market simple power supply designs. The

ISL8117 uses internal loop compensation and single

resistor settings for other functions such as operating

frequency and overcurrent protection. Its current

• Forced PWM

• Adaptive shoot-through protection

• No external current sense resistor

○ Use lower MOSFET r

• Complete protection

DS(ON)

○ Overcurrent, overvoltage, over-temperature,

undervoltage

○ Pb-free (RoHS compliant)

Applications

mode control with V feed-forward enables it to cover

• PLC and factory automation

• Amusement machines

• Security surveillance

• Servers and data centers

• Switchers and routers

• Telecom and datacom

• LED panels

various applications even with fixed internal

compensations. The unique DEM/Skipping mode at

light-load dramatically lowers standby power

consumption with consistent output ripple over

different load levels.
