Advanced Single Universal Pulse-Width Modulation
(PWM) Controller
ISL8130
The ISL8130 is a versatile controller that integrates control,
output adjustment, monitoring and protection functions into a
single package for synchronous buck, standard boost, SEPIC
and flyback topologies.
The ISL8130 provides simple, single feedback loop, voltage
mode control with fast transient response. The output voltage
of the converter can be precisely regulated to as low as 0.6V.
The switching frequency is adjustable from 100kHz to 1.4MHz.
The error amplifier features a 15MHz gain-bandwidth product
and 6V/μs slew rate that enables fast transient response. The
PWM duty cycle ranges from 0% to 100% in transient
conditions. The capacitor from the ENSS pin to ground sets
soft-start slew rate.
The ISL8130 monitors the output voltage and generates a
PGOOD (power-good) signal when soft-start sequence is
complete and the output is within regulation. A built-in
overvoltage protection circuit prevents the output voltage from
going typically above 115% of the set point. For a buck and
buck-boost configuration, protection from overcurrent
conditions is provided by monitoring the r DS(ON) of the upper
MOSFET to inhibit the PWM operation appropriately. This
approach improves efficiency by eliminating the need for a
current sensing resistor. For other topologies, overcurrent
protection is achieved using a current sensing resistor.
