FN9052.2
Dual 5V Synchronous Buck Pulse-Width
Modulator (PWM) Controller for DDRAM
Memory V DDQ and V TT Termination
The ISL6530 provides complete control and protection for
dual DC-DC converters optimized for high-performance
DDRAM memory applications. It is designed to drive low
cost N-channel MOSFETs in synchronous-rectified buck
topology to efficiently generate 2.5V V DDQ for powering
DDRAM memory, V REF for DDRAM differential signalling,
and V TT for signal termination. The ISL6530 integrates all of
the control, output adjustment, monitoring and protection
functions into a single package.
The V DDQ output of the converter is maintained at 2.5V
through an integrated precision voltage reference. The V REF
output is precisely regulated to 1/2 the memory power
supply, with a maximum tolerance of ± 1% over temperature
and line voltage variations. V TT accurately tracks V REF .
During V2_SD sleep mode, the V TT output is maintained by
a low power window regulator.
The ISL6530 provides simple, single feedback loop, voltage-
mode control with fast transient response. It includes two
phase-locked 300kHz triangle-wave oscillators which are
displaced 90 o to minimize interference between the two
PWM regulators. The regulators feature error amplifiers with
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 ISL6530 protects against over-current conditions by
inhibiting PWM operation. The ISL6530 monitors the current
in the V DDQ regulator by using the r DS(ON) of the upper
MOSFET which eliminates the need for a current sensing
resistor.
