The LMZ22003 SIMPLE SWITCHER© power module is an easy-to-use step-down DC-DC solution capable of driving up to 3A load. The LMZ22003 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ22003 can accept an input voltage rail between 6V and 20V and 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 under-voltage lockout, output over-voltage protection, short-circuit protection, output current limit, and allows startup into a pre-biased output. The sync input allows synchronization over the 650 to 950 kHz switching frequency range.
18W maximum total output power Up to 3A output current Input voltage range 6V to 20V Output voltage range 0.8V to 6V Efficiency up to 92%
Integrated shielded inductor Simple PCB layout Frequency synchronization input (650 kHz to 950 kHz) Flexible startup sequencing using external soft-start, tracking and precision enable Protection against inrush currents and faults such as input UVLO and output short circuit – 40°C to 125°C junction temperature range Single exposed pad and standard pinout for easy mounting and manufacturing Fast transient response for powering FPGAs and ASICs Fully enabled for Webench® Power Designer Pin compatible with LMZ23605/LMZ23603/LMZ22005
