Overview
Description
The ISL73007SEH is a radiation hardened Point-of-Load (POL) buck regulator that provides up to 3A 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 ISL73007SEH has an internally configured switching frequency of 500kHz. The ISL73007SEH switching frequency can be adjusted from 300kHz to 1MHz using an external resistor.
The ISL73007SEH integrates high-side (P-Channel) and low-side (N-Channel) power FETs. There are options for external or internal compensation, switching frequency, and slope control, that can be implemented with a minimum of external components reducing the BOM count and design complexity.
The ISL73007SEH includes a comprehensive suite of operational features and protections, including preset undervoltage, overvoltage, and overcurrent protections, power-good, soft-start, and over-temperature.
The ISL73007SEH is designed to operate across the temperature range of -55 °C to +125 °C and is available in a 14-lead ceramic dual in-line flat package (CDFP) and die form.
