3 Description
The LMZ23610 SIMPLE SWITCHER^® power module
is an easy-to-use step-down DC-DC solution capable
of driving up to 10-A load. The LMZ23610 is available
in an innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ23610 can accept an input voltage rail
between 6 V and 36 V and can deliver an adjustable
and highly accurate output voltage as low as 0.8 V.
The LMZ23610 only requires two external resistors
and three external capacitors to complete the power
solution.
The LMZ23610 is a reliable and robust design with
the following protection features: thermal shutdown,
input undervoltage lockout, output overvoltage
protection, short circuit protection, output current limit,
and the device allows start-up into a prebiased
output. The sync input allows synchronization over
the 350- to 600-kHz switching frequency range.
