Ultra-low-power MOSFETs prolong battery life
Intersil has launched its advanced new DenseTrench power MOSFET family of discrete power devices designed for higher-efficiency low-voltage power switching applications.
Programmable up-converter simplifies basestations
Intersil has added a new highly integrated quad up-convertor to its CommLinkT family of digital radio ICs for fixed basestation applications.
Intersil is the only supplier to offer two alternative precision core regulation solutions for the Intel Pentium M processor.
The ISL6216 multiphase PWM controller, combined with external mosfet drivers such as Intersil's ISL6207, offers design flexibility for up to two phases of core power current sharing up using external mosfet drivers.
The ISL6217 provides single- and/or two-phase control using two integrated mosfet drivers, reducing external component count and conserving board space and cost.
In addition to core power regulation solutions, Intersil also provides high efficiency PWM controllers for Intel's Centrino mobile technology platform memory, interface control hub chipset and DDR SDRAM.
Features include precision voltage regulation to 0.8% system accuracy over temperature for the ISL6217 and 1% for the ISL6216.
They also feature a 6bit microprocessor voltage identification input from 0.700 to 1.708V in 16mV steps, plus programmable droop and core voltage slew rates.
Users can program switching frequency from 250kHz to 1MHz per phase.
The devices provide direct interfacing with system logic for deep and deeper sleep modes.
Both devices allow lossless current sensing for improved efficiency and reduced board area, or alternatively discrete resistor sensors can be used.
"Notebook manufacturers have demonstrated battery run times of over 5 hours when running Intel Pentium M processor-based platforms using Intersil's power management solutions", said Dean Henderson, Director for Intersil's Portable Power Management Products.
"These new platforms will significantly enhance the freedom of mobility for end users".
