Description

The LMZ23603 SIMPLE SWITCHER®power module is an easy-to-use step-down DC-DC solution capable of driving up to 3-A load. The LMZ23603 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering. The LMZ23603 can accept an input voltage rail between 6 V and 36 V and deliver an adjustable and highly accurate output voltage as low as 0.8 V. The LMZ23603 only requires two external resistors and three external capacitors to complete the power solution. The LMZ23603 is a reliable and robust design with the following protection features: thermal shutdown, programmable 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 650-kHz to 950-kHz switching frequency range.
