3 Description
The LMZ23608 SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution capable
of driving up to 8-A load. The LMZ23608 is available
in an innovative package that enhances thermal
performance and allows for hand or machine
soldering.
The LMZ23608 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 LMZ23608 only requires two external resistors
and three external capacitors to complete the power
solution.
The LMZ23608 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 allows start-up into a prebiased output. The sync
input allows synchronization over the 350 to 600-kHz
switching frequency range.
