FN4998.3
Buck and Synchronous-Rectifier
Pulse-Width Modulator (PWM) Controller
The ISL6525 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 ISL6525 integrates all of the control, output
adjustment, monitoring and protection functions into a single
package. A programmable delay time for the PGOOD signal
makes it especially suitable for the VTT regulation in VRM8.5
applications.
The output voltage of the converter can be precisely
regulated to as low as 1.20V, with a maximum tolerance of
± 1% over temperature and line voltage variations.
The ISL6525 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% to 100%.
The ISL6525 protects against over-current conditions by
inhibiting PWM operation. The ISL6525 monitors the current
by using the r DS(ON) of the upper MOSFET which eliminates
the need for a current sensing resistor.
