ISL6522
FN9030.8
Buck and Synchronous Rectifier
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.
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.
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/ μ s slew rate which enables high converter bandwidth for
fast transient performance. The resulting PWM duty ratio
ranges from 0–100%.
The ISL6522 protects against overcurrent conditions by
inhibiting PWM operation. The ISL6522 monitors the current
by using the r DS(ON) of the upper MOSFET which eliminates
the need for a current sensing resistor.
