3V to 20V, Two-Phase Buck PWM Controller with Integrated 4A MOSFET Drivers

The ISL8121 is a two-phase buck PWM controller

featuring an input voltage range of 3V to 20V and

Features

• Integrated Two-Phase Power Conversion

integrated MOSFET drivers. Precision voltage

regulation is provided for point-of-load and other high-

current applications that require efficient and compact

implementation. Multiphase buck converter

architecture uses interleaved timing to multiply

channel ripple frequency allowing smaller filter

inductors and reducing input and output ripple currents

due to the ripple cancellation effect. Lower ripple

results in fewer input and output capacitors. Smaller

and low cost transistors can be used resulting from the

higher efficiency and reduced power dissipation.

• Precision Output Voltage Regulation

- 0.8% System Accuracy Over-Temperature

(Industrial)

- Differential Remote Voltage Sensing for

Increased Voltage Sensing Accuracy

• Shunt Regulator for Wide Input Power Conversion

- 5V and Higher Bias

- Up to 20V Power Down-Conversion

• Precision Channel Current Sharing

The ISL8121 offers an internal 0.6V reference with a

system regulation accuracy of ±0.8% (Industrial

Temperature range), an optional external reference

input, and user-adjustable switching frequency. Unity

gain differential amplifier targeted at remote voltage

sensing capability enhances the regulation. A power

good signal (PGD) is issued when the output voltage is

within the regulated window. An internal shunt

regulator with optional external connection capability

extends the operational input voltage range. For

applications requiring voltage tracking or sequencing,

the ISL8121 offers a host of possibilities, including

coincidental, ratiometric, or offset tracking, as well as

sequential start-ups, user adjustable for a wide range

of applications.

- Loss-Less r

DS(ON)

Current Sampling

• Integrated High Capable 4A Drivers

• 0.6V Internal Reference

• Full Spectrum Voltage Tracking

- Coincidental, Ratiometric, or Offset

• Sequential Start-up Control

• Selectable Switching Frequency up to 2MHz Per

Phase

• Fast Transient Recovery Time

• Overcurrent Protection

• Overvoltage Protection

• Capable of Start-up in a Pre-Biased Load

• QFN Packages:

- QFN - Compliant to JEDEC PUB95 MO-220

- QFN - Quad Flat No Leads - Package Outline

Additional features include overvoltage and

overcurrent protection. Overcurrent protection can be

tailored to various applications with no need for

additional parts. The ISL8121 uses cost and space-

saving r

sensing for channel current balance,

- Near Chip Scale Package footprint, which

dynamic voltage positioning, and overcurrent

protection. Channel current balancing is automatic and

accurate with the integrated current-balance control

system.

improves PCB efficiency and has a thinner profile

• Pb-Free Available (RoHS Compliant)

Applications

• General Purpose High Current DC/DC Converters

• High Current, Low Voltage FPGA/ASIC DC/DC

Converters

• Telecom System
