FN9122.2

Buck and Synchronous Rectifier

Features

• Drives two N-Channel MOSFETs

Pulse-Width Modulator (PWM) Controller

The ISL6522A provides complete control and protection for

a DC-DC converter optimized for high-performance

microprocessor applications. It is designed to drive two

N-Channel MOSFETs in a synchronous rectified buck

topology. The ISL6522A integrates all of the control, output

adjustment, monitoring and protection functions into a single

package.

• Operates from +5V or +12V input

• Simple single-loop control design

- Voltage-mode PWM control

• Fast transient response

- High-bandwidth error amplifier

- Full 0-100% duty ratio

The output voltage of the converter can be precisely

regulated to as low as 0.8V, with a maximum tolerance of

±0.5% over temperature and line voltage variations.

• Excellent output voltage regulation

- 0.8V internal reference

- ±0.5% over line voltage and temperature

The ISL6522A provides simple, single feedback loop,

voltage-mode control with fast transient response. It includes

a 200kHz free-running triangle-wave oscillator that is

adjustable from below 50kHz to over 1MHz. The error

amplifier features a 15MHz gain-bandwidth product and

6V/µs slew rate which enables high converter bandwidth for

fast transient performance. The resulting PWM duty ratio

ranges from 0–100%.

• Overcurrent fault monitor

- Does not require extra current sensing element

- Uses MOSFETs r

DS(ON)

• Converter can source and sink current

• Small converter size

- Constant frequency operation

- 200kHz free-running oscillator programmable from

50kHz to over 1MHz

The ISL6522A protects against overcurrent conditions by

inhibiting PWM operation. The ISL6522A monitors the

• 14 Ld SOIC and 16 Lead 5x5mm QFN Packages

• QFN Package

- Compliant to JEDEC PUB95 MO-220 QFN-Quad Flat

No Leads-Product Outline.

- Near Chip-Scale Package Footprint; Improves PCB

Efficiency and Thinner in Profile

current by using the r

of the upper MOSFET which

DS(ON)

eliminates the need for a current sensing resistor.

NOTE: Intersil Pb-free 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.

*Add “-T” suffix for tape and reel.

CCAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
