Intersil Expands DC/DC Controller Portfolio With Complete Solutions for Embedded and Low Power CPU/GPU Cores

Flexible ISL95835 and ISL95837 Feature R3 Modulation to Provide Fastest Transient Response; Compact Package Saves Cost and Space

MILPITAS, CA--(Marketwire - Sep 19, 2011) - 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.
