ISL6522B
Buck and Synchronous Rectifier
Pulse-Width Modulator (PWM) Controller
The ISL6522B 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 ISL6522B 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 ISL6522B 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 perform-
ance. The resulting PWM duty ratio ranges from 0-100%.
The ISL6522B protects against overcurrent conditions by
inhibiting PWM operation. The ISL6522B monitors the
current by using the r
DS(ON)
of the upper MOSFET which
eliminates the need for a current sensing resistor.
