42V Quad Monolithic Synchronous Step-Down Regulator
with 30ВµA Quiescent Current
Design Note 544

Introduction
Industrial and automotive applications require robust,
easy-to-use, compact DC/DC converters to produce
a variety of low voltage power supplies. The LT8602
monolithic quad synchronous step-down converter in
a 6mm Г— 6mm package is capable of providing four
outputs from a wide input range of 3V to 42V. It is
versatile and easy to use with features such as low
EMI and adjustable operating frequency up to 2.2MHz.
It consumes only 30ВµA quiescent current from the
input source even when regulating the outputs.
Small Size, Low EMI, Quad Step-Down
Solution
The LTВ®8602 integrates two high voltage (HV) and
two low voltage (LV) synchronous regulators in a
QFN (6mm Г— 6mm) package. Replacing external
Schottky diodes with internal synchronous switches
minimizes the solution size and also increases efficiency, reducing power dissipation. Figure 1. Top Center View of
the Demo Board DC1949A …
