The ISL8118 is a single-phase PWM controller featuring an input voltage range of +3. 3V to +20V and integrated MOSFET drivers. Utilizing voltage-mode operation with input voltage feed-forward compensation, the ISL8118 maintains a constant loop gain, providing optimal transient response for applications with a wide input operating voltage range. The output voltage can be precisely regulated down to 0. 591V with a system tolerance of ±1. 0% over the industrial temperature range and line and load variations. A external reference input is provided to bypass the internal reference for voltage tracking or DDR memory applications. The compact 28 Ld 5x5 QFN package, integrated linear regulator as well as the external linear regulator drive option, integrated differential remote sense amplifier and integrated voltage margining with adjustable upper and lower settings decrease external component count and reduce board space requirements. Programmable soft-start with pre-biased load capability, adjustable operating frequency from 250kHz to 2MHz, sourcing and sinking overcurrent protection, overvoltage and undervoltage protection, and power-good indication with programmable delay combine to make the ISL8118 a superior choice for many power supply systems.
