Overview
Description
The ISL73006SLH is a radiation hardened point-of-load (POL) buck regulator that provides up to 1A of output current capability with an input voltage ranging from 3V to 18V. The device uses constant frequency peak current mode control architecture for fast loop transient response. The device uses internal compensation or an external Type-II compensation to optimize performance and stabilize the loop. The ISL73006SLH has a default switching frequency of 500kHz.
The ISL73006SLH integrates high-side (P-channel) and low-side (N-channel) power FETs. There are options for external or internal compensation and slope control that can be implemented with a minimum of external components reducing the BOM count and design complexity.
The ISL73006SLH includes a comprehensive suite of operational features and protections, including preset undervoltage, overvoltage, overcurrent protections, power-good, soft-start, and over-temperature.
The ISL73006SLH operates across the temperature range of -55 °C to +125 °C and is available in a 10-lead ceramic dual in-line flat package (CDFP) and die form.
