ISL8115

概要

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.
