ISL8115
High Voltage Synchronous Buck PWM Controller with Integrated Gate Driver and
Current Sharing Capability
The ISL8115 is a synchronous buck PWM controller with
current sharing capability. The current sharing function allows
multiple modules to be connected in parallel to achieve higher
output current and to reduce input and output ripple current,
resulting in fewer components and reduced output dissipation.
Utilizing voltage-mode control with input voltage feed-forward
compensation, the ISL8115 maintains a constant loop gain for
optimal transient response, especially for applications with a
wide input voltage range.
The ISL8115 protects against overcurrent conditions by
inhibiting the PWM operation while monitoring the current
with DCR of the output inductor, or a precision resistor. It also
has a pre-POR overvoltage protection option, which provides
some protection to the load if the upper MOSFET(s) is shorted.
The ISL8115 features remote ground sensing, programmable
input voltage UVLO, output under/overvoltage protection,
power-good indication, and fault Hand Shake capability.
