Single 12V Input Supply Dual Regulator —

Synchronous Rectified Buck PWM and

Linear Power Controller

Features

• Single 12V bias supply (no 5V supply is required)

• Provides two regulated voltages

- One synchronous rectified buck PWM controller

- One linear controller

The ISL6549 provides the power control and protection for

two output voltages in high-performance applications. The

dual-output controller drives two N-Channel MOSFETs in a

synchronous rectified buck converter topology and one

N-Channel MOSFET in a linear configuration. The controller is

ideal for applications where regulation of both the processing

unit and memory supplies is required.

• Both controllers drive low cost N-Channel MOSFETs

• Small converter size

- Adjustable frequency 150kHz to 1MHz

- Small external component count

• Excellent output voltage regulation

- Both outputs: ±1% over temperature

The synchronous rectified buck converter incorporates

simple, single feedback loop, voltage-mode control with fast

transient response. Both the switching regulator and linear

regulator provide a maximum static regulation tolerance of

±1% over line, load, and temperature ranges. Each output is

user-adjustable by means of external resistors.

• 12V down conversion

• PWM and linear output voltage range: down to 0.8V

• Simple single-loop voltage-mode PWM control design

• Fast PWM converter transient response

- High-bandwidth error amplifier

An integrated soft-start feature brings both supplies into

regulation in a controlled manner. Each output is monitored

via the FB pins for undervoltage events. If either output drops

below 75% of the nominal output level, both converters are

shut off and go into retry mode.

• Undervoltage fault monitoring on both outputs

• Pb-free plus anneal available (RoHS compliant)

Applications

The ISL6549 is available in a 14 Ld SOIC package,

16 Ld QSOP, or 16 Ld 4x4 QFN packages.
