The LMZ22003TZ is a SIMPLE SWITCHER® Power Module with 20V maximum input voltage. The power module is an easy-to-use step-down DC-DC solution capable of driving up to 3A load. The LMZ22003 enhances thermal performance and allows for hand or machine soldering. The LMZ22003 can accept an input voltage rail between 6 and 20V and can deliver an adjustable and highly accurate output voltage as low as 0.8V. The LMZ22003 only requires two external resistors and three external capacitors to complete the power solution. The LMZ22003 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 this device allows start-up into a pre-biased output. The sync input allows synchronization over the 650 to 950kHz switching frequency range.
