ISL6522A
Data Sheet
April 13, 2005
FN9122.2
Buck and Synchronous Rectifier
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.
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.
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/ μ s slew rate which enables high converter bandwidth for
fast transient performance. The resulting PWM duty ratio
ranges from 0–100%.
The ISL6522A protects against overcurrent conditions by
inhibiting PWM operation. The ISL6522A monitors the
current by using the r DS(ON) of the upper MOSFET which
eliminates the need for a current sensing resistor.
