ISL8130IRZ-TK

DC DC Switching Controllers Overview

The ISL8130IRZ-TK is an obsolete advanced single universal pulse-width modulation (PWM) controller manufactured by Renesas Electronics Corporation. It integrates control, output adjustment, monitoring, and protection functions for synchronous buck, standard boost, SEPIC, and flyback topologies. The device supports a wide input range of 4.5V to 28V and features a programmable switching frequency adjustable from 100 kHz to 1.4 MHz. It includes a high-bandwidth error amplifier with a 15 MHz gain-bandwidth product and 6 V/µs slew rate for fast transient response. The controller offers overvoltage, overcurrent, and overtemperature protection, along with a power-good signal generation capability.
