Buck and Synchronous Rectifier

Features

• Drives two N-Channel MOSFETs

Pulse-Width Modulator (PWM) Controller

The ISL6522 provides complete control and protection for a

DC-DC converter optimized for high-performance micro-

processor applications. It is designed to drive two N-Channel

MOSFETs in a synchronous rectified buck topology. The

ISL6522 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

±1% over temperature and line voltage variations.

• Excellent output voltage regulation

- 0.8V internal reference

The ISL6522 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%.

- ±1% over line voltage and temperature

• 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

The ISL6522 protects against overcurrent conditions by

inhibiting PWM operation. The ISL6522 monitors the current

50kHz to over 1MHz

by using the r

of the upper MOSFET which eliminates
