FN6325.0

3.3V to 20V, Single-Phase PWM Controller

with Integrated 2A/4A MOSFET Drivers

Features

• Wide Input Voltage Range: +3.3V to +20V

• High-Speed 2A/4A MOSFET Gate Drivers That Operate

from 2.9V to 5.6V

The ISL8118 is a single-phase PWM controller featuring an

input voltage range of +3.3V to +20V and integrated MOSFET

drivers. Utilizing voltage-mode operation with input voltage

feed-forward compensation, the ISL8118 maintains a constant

loop gain, providing optimal transient response for applications

with a wide input operating voltage range.

• 0.591V Internal Reference

• External Reference Input

• Input Voltage Feed-forward Compensation

• Internal Linear Regulator

The output voltage can be precisely regulated down to

0.591V with a system tolerance of ±0.85% over the

commercial temperature range and line and load variations.

A external reference input is provided to bypass the internal

reference for voltage tracking or DDR memory applications.

The compact 28 Ld 5x5 QFN package, integrated linear

regulator as well as the external linear regulator drive option,

integrated differential remote sense amplifier and integrated

voltage margining with adjustable upper and lower settings

decrease external component count and reduce board

space requirements.

• External Linear Regulator Drive Available

• High System Accuracy:

- ±0.85% over the range of 0°C to +70°C

- ±1.25% over the range of -40°C to +85°C

• Programmable Operating Frequency from 250kHz to

2MHz

• Programmable Soft-Start with Pre-biased Load Capability

• Integrated Unity-Gain Differential Remote Sense Amplifier

• Enable Input with Voltage Monitoring Capability

• Integrated Voltage Margining with Independent Upper and

Lower Settings

Programmable soft-start with pre-biased load capability,

adjustable operating frequency from 250kHz to 2MHz,

sourcing and sinking overcurrent protection, overvoltage and

undervoltage protection, and power-good indication with

programmable delay combine to make the ISL8118 a

superior choice for many power supply systems.

• Overvoltage and Undervoltage Protection

• Low-Side and High-Side MOSFET Current Sensing

• Overcurrent Protection for Sourcing and Sinking Currents

• Power-Good Indicator with Programmable Delay

• Compact 28 Ld 5x5 QFN Package

• Pb-Free Plus Anneal Available (RoHS Compliant)

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
