Intersil’s Integrated FET Regulators Support Input Voltages Up To 60V And Spikes to 100V
The ISL8560 supports an input voltage range of 9V to 60V with programmable output voltages from 1.21V to 55V while the ISL8540 has an input voltage range of 9V to 40V with a programmable output voltage range of 1.21V to 35V. This high flexibility makes them ideally suited for a variety of applications such as high voltage industrial, telecom/datacom and automotive power applications.
These devices also have the capability to manage transient spikes of up to 100V for 400mS, adding critical protection against spikes.
The ISL8540 and ISL8560 provide industry-leading features including separate EN and Power Good for output sequencing, adjustable switching frequency and external frequency synchronization from 100kHz to 600kHz. Both devices contain protection features such as over-temperature, undervoltage, pulse-by-pulse hiccup mode overcurrent and short circuit protections. These features add flexibility, increase efficiency, reduce EMI and improve system reliability against adverse fault conditions.
The ISL8540 and ISL8560 include an integrated BOOT diode and high-side, integrated power DMOS low-resistance transistor capable of supporting up to 2A continuous load current to improve efficiency and accelerate switching speeds. The internal reference of 1.21V is accurate to +/-1% over industrial temperature range (-40degC to 85degC). These features, along with input voltages to support 12V, 24V, 36V and 48V applications, make these devices the industry’s most flexible and easy-to-use, plug-and-play power solutions for most point-of-load applications.
The ISL8540 is available in a 20-lead HTSSOP package while the ISL8560 comes in a 20-lead QFN. Both devices meet Pb-free plus anneal standards and are RoHS compliant.
