ISL6520B
Single Synchronous Buck Pulse-Width
Modulation (PWM) Controller
The ISL6520B makes simple work out of implementing a
complete control scheme for a DC-DC stepdown converter.
Designed to drive N-channel MOSFETs in a synchronous
buck topology, the ISL6520B integrates the control, output
adjustment and monitoring functions into a single 8-Lead
package.
The ISL6520B 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%.
