ISL8118IRZ - Renesas Electronics

Description: 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 ex
