Intersil Introduces Industry’s First Fully-Integrated Synchronous Point-of-Load (POL) Regulator for Low-Voltage ICs in Rad-Hard and High-Reliability Systems
Provides Highest Reliability and Efficiency; Small Footprint Enables Fewer External Components; Meets Mil Temp Range
MILPITAS, CA, Feb 10, 2010 – Intersil
Corporation (NASDAQ Global Select: ISIL),
a world leader in the design and manufacture of high-performance analog
and mixed-signal semiconductors, today released the industry’s
most reliable, efficient, single-chip POL synchronous buck regulator for
satellite systems, nuclear reactor equipment, down hole drilling applications,
and other high-reliability systems.
The new ISL70001SRH is
a complete power solution designed for use in systems that required POL power
in extreme temperature and radiation-intensive environments. It integrates
6A power MOSFETs, MOSFET drivers and a 1MHz PWM controller in a single compact
package. Two ISL70001SRH devices can be synchronized 180 degrees out-of-phase
to reduce input RMS ripple current and the size of input filter components.
The regulator offers superior single event transient (SET) performance, with <1
pulse perturbation at the switching node up to an LET = 86.4MeV/mg/cm squared.
Total ionizing dose (TID) capacity is 100Krads(Si) and is offered in Class
V and Class Q manufacturing flows electrically screened to DSCC SMD#
5962-09225. The combination of excellent SET and TID characteristics
makes the ISL70001SRH a logical design choice to power many of today’s
small form-factor applications.
The ISL70001SRH operates over an input voltage range of 3V to 5.5V and provides
a tightly regulated output voltage that is externally adjustable from 0.8V
up to 85% of the input voltage. Output current capability is 6A for TJ up
to +145 degrees C. An analog soft-start circuit controls start-up, and
can be adjusted from approximately 2ms to 200ms using an external capacitor.
In addition, the ISL70001SRH incorporates fault protection for the regulator,
with protection including input undervoltage, output undervoltage and output
overcurrent.
Pricing and Availability
Intersil offers Class V and Class Q manufacturing flows for the ISL70001SRH,
which comes in a 48-lead ceramic quad flatpack (CQFP) and is also offered
in class V die. Sample quantity pricing for the ISL70001SRHVF starts at $4,546
each for less than 25 pieces. The ISL70001SHR/proto is priced at $857.
