Design Note 387

Introduction
Easy-to-use and compact point-of-load power supplies
are necessary in systems with widely distributed, high
current, low voltage loads. The LTCВ® 3415 provides a
compact, simple and versatile solution. It includes a pair
of integrated complementary power MOSFETs (32mО©
top and 25mО© bottom) and requires no external sense
resistor. A complete design requires an inductor and
input/output capacitors, and thatвЂ™s it. The result is a fast,
constant frequency, 7A current mode DC/DC switching
regulator.
Features
The overall solution is extremely compact since the
LTC3415вЂ™s 5mm Г— 7mm QFN package footprint is small
and its high operating frequency of 1.5MHz allows the
use of small low-proп¬Ѓle surface mount inductors and
ceramic capacitors. For loads higher than 7A, multiple
LTC3415s can be cascaded to share the load while running mutually anti-phase, which reduces overall ripple
at both the input and the output.
Other features include: Spread spectrum operation to reduce system noise Output tracking for controlled VOUT ramp-up and …
