Tiger Zhou and David Canny
Introduction
Typical industrial and automotive applications require
multiple high current, low voltage power supply solutions
to drive everything from disc drives to microprocessors. For many of these applications, particularly those
that have size constraints, the LT3501В® dual step-down
converter is an attractive solution because itвЂ™s compact
and inexpensive compared to a 2-chip solution. The dual
converter accommodates a 3V to 25V input voltage range
and is capable of supplying up to 3A per channel. The
circuit in Figure 1 produces 3.3V and 1.8V.
LT3501 Dual Converter Features The LT3501 is feature-rich and comes with internal 3.5A
switches and sense resistors to minimize solution size
and cost. The LT3501 operates at a п¬Ѓxed frequency between
250kHz and 1.5MHz, programmed using a single resistor or synchronized to an external clock, allowing
optimization of efп¬Ѓciency and solution size. A 180В° phase relationship between the channels is
maintained to reduce input voltage ripple and input
capacitor size. Independent input voltage, feedback, soft-start and
power good functions for each converter simplify the
implementation of all the tracking and sequencing
options available. Minimum input-to-output voltage ratios are extended …
