Intersil Expands DC/DC Controller Portfolio With Complete Solutions for Embedded and Low Power CPU/GPU Cores
September 19 2011 - 10:00AM
Marketwired
Intersil Corporation (NASDAQ: ISIL) today expanded its portfolio of
industry leading multi-phase DC/DC controllers by introducing the
ISL95835 and ISL95837. Both controllers provide a complete low cost
solution for CPU and GPU core power while delivering best-in-class
transient response and efficiency. Each complies with Intel's
IMVP-7/VR12™ specification for smart voltage regulation to reduce
power dissipation in the second-generation lntel® Core-i5/i7
processors.
Both the ISL95835 and ISL95837 are the industry's smallest
solutions available and offer combined functionality and reduced
pin count, saving valuable board space and reducing the total bill
of materials. The ISL95837 has been optimized for lower power, thin
and light applications.
The controllers are based on Intersil's Robust Ripple Regulator
(R3)™ technology, a hybrid of fixed-frequency PWM control and
variable-frequency hysteretic control that delivers the industry's
fastest transient response. The R3 modulator delivers faster
transient settling time than typical modulators and automatically
adapts switching frequency to optimize light load efficiency.
Features and Specifications
- The ISL95835 includes two internal MOSFET drivers for a 3+1
solution and can be configured as a 3-, 2- or 1-phase VR
- The ISL95837 can be considered as an ISL95835 dedicated for a
1+1 application with an output of 1-phase VR, maximizing
flexibility
- Both devices operate in diode (or sleep) mode when a CPU enters
light load modes for added efficiency and battery life
- Accept input voltages from 4.5V to 25V and deliver output
voltages from 0.25V to 1.5V
Pricing and Availability Both the ISL95835
and ISL95837 are currently available in 40-pin 5mm x 5mm QFN
packages. Pricing for the ISL9535 is $3.28 for 1,000-unit
quantities; pricing for the ISL95837 is $3.08 for 1,000-unit
quantities.
