Data Sheet
April 3, 2007
FN9009.6
Single Synchronous Buck Pulse-Width
Modulation (PWM) Controller
The ISL6520 makes simple work out of implementing a
complete control and protection scheme for a DC/DC
stepdown converter. Designed to drive N-Channel
MOSFETs in a synchronous buck topology, the ISL6520
integrates the control, output adjustment, monitoring and
protection functions into a single 8 Lead package.
The ISL6520 provides simple, single feedback loop, voltage-
mode control with fast transient response. The output
voltage can be precisely regulated to as low as 0.8V, with a
maximum tolerance of ± 1.5% over-temperature and line
voltage variations. A fixed frequency oscillator reduces
design complexity, while balancing typical application cost
and efficiency.
The error amplifier features a 15MHz gain-bandwidth
product and 8V/ μ s slew rate which enables high converter
bandwidth for fast transient performance. The resulting
PWM duty cycles range from 0% to 100%.
Protection from over-current conditions is provided by
monitoring the r DS(ON) of the upper MOSFET to inhibit PWM
operation appropriately. This approach simplifies the
implementation and improves efficiency by eliminating the
need for a current sense resistor.
