Linear Technology has introduced the LTC2927, a single power supply tracking controller that simplifies the tracking and sequencing requirements of complex distributed power architectures.

has introduced the LTC2927, a single power supply tracking controller that simplifies the tracking and sequencing requirements of complex distributed power architectures.

Housed in an eight-lead SOT-23 or 3mm x 2mm DFN package, the device can be placed at the point of load. By minimising the trace length to the sensitive feedback node of a DC/DC converter, the LTC2927 reduces losses caused by voltage drops and overcomes noise sensitivity and EMI issues.

The LTC2927 introduces current into the feedback node of an independent supply and causes its output to track another supply or master signal. A simple resistor configuration yields a ramp-up and ramp-down with differing ramp rates, voltage offsets or time delays relative to the master signal. This enables a variety of power (supply) profiles for digital logic circuits during power up as well as power down. Linear claims the LTC2927 is ideally suited for systems utilising FPGAs, CPLDs or DSPs.
