Multiphase DC-DC Controller Pushes Accuracy And Bandwidth Limits
Speed and accuracy don’t always go hand-in-hand
in DC/DC converter systems—that is, until now. The
LTC3811 is a dual output, fi xed frequency current mode
DC/DC switching regulator controller designed for one of
today’s most demanding power supply applications: high
current, low voltage processor core supplies.

Tiny Amplifiers Drive Heavy Capacitive Loads at Speed
Parasitic capacitance lurks behind every corner of an
electronic circuit. FET gates, cabling, ground and power
planes all add to the Farad bottom line. When the capacitive
load gets heavy in high speed circuits, careful op amp
selection is paramount for optimizing slew rate, current
output capability, power dissipation, and feedback loop
stability.

Pushbutton On/Off Controller With Failsafe Voltage Monitoring
Have you had the exasperating experience of a laptop or PDA defiantly not responding to your commands? You frantically press key after key, but to no avail. As hope turns to anger (but just before you throw the company’s laptop through the window) you slam your finger against the on/off power button.

6-Channel SAR ADCs for Industrial Monitoring and Portable
The 14-bit LTC2351-14 is a 1.5 Msps, low-power SAR ADC with six simultaneously sampled differential input channels. It operates from a single 3-V supply and features six independent sample-and-hold amplifiers and a single ADC. The single ADC with multiple S/HAs enables excellent range match (1 mV) between channels and channel-to-channel skew (200 ps).

High Power PoE PD Interface With Integrated Flyback Controller
To this day, Power over Ethernet (PoE) continues to gain popularity in today’s networking world. The 12.95 W delivered to the powered device (PD) input supplied by the Power Sourcing Equipment (PSE) is a universal supply. Each PD provides its own dc-dc conversion from a nominal 48-V supply, thus eliminating the need for a correct-voltage wall adapter.
