Intersil's Integrated FET Regulators Support Input Voltages Up To 60V And Spikes to 100V
MILPITAS, CA, July 23, 2007 Intersil Corporation (NASDAQ Global Select: ISIL) today announced the release of a new family of high efficiency, 2A integrated FET step down DC/DC switching regulators that support wide operating input voltages and can handle transient spikes up 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 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 overcurrent and hiccup-mode short circuit protections.
All of these features add flexibility, increase efficiency 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 (-40°C to +85°C). These features, along with input voltages to support 12V, 24V, 36V, 48V and 60V applications, make these devices the industrys 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.
