Power Supply Works with FET Drivers, DrMOS and Power
Blocks for Flexible Placement Near Microprocessors
Theo Phillips As microprocessors demand progressively more current at lower voltages, it becomes
important to minimize conduction losses by placing the power supply as close to
the load as possible. This increases the value of every square millimeter of board
space near the loadвЂ”particularly when multiple power stages are used. It is also
important to locate the DC/DC controller away from high current paths, which can
be difficult when the MOSFET gate drivers are in the controller package, because the
gate traces must also be kept short. Sometimes the best solution is to use external
power train devices or discrete N-channel MOSFETs and associated gate drivers.
The LTC3860 is a dual output step-down
DC/DC controller designed to work in
conjunction with drivers or power train
devices such as DrMOS and power blocks,
enabling flexible design configurations
with PolyPhaseВ® operation. Up to 12
stages can be paralleled to increase output
current and clocked out of phase to minimize input and output filtering (FigureВ 1).
In PolyPhase configurations, both output voltage (VOUT) and ground terminals
are monitored using a single differential
amplifier, enabling tight regulation even
where IR losses occur through vias, trace
runs and interconnects. Regulation is …
