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.
