illustrate
The LMZ22010's SIMPLE SWITCHER © power module is an easy-to-use step-down DC-DC solution capable of driving loads up to 10A. LMZ22010 is an innovative solution that enhances thermal properties and allows for manual or machine welding.
LMZ22010 can accept input voltage rails between 6V and 20V and provide adjustable and highly accurate output voltages as low as 0.8V. LMZ22010 only need two external resistors and an external capacitor to complete the power solution. LMZ22010 is a safe, reliable, and powerful design with the following protection features: thermal shutdown, programmable input undervoltage lockout, output overvoltage protection, short-circuit protection, output current limiting, and allows entry into pre-biased output start-up.
The SYNC input allows for a switching frequency range of more than 314 to 600 kHz and synchronization of up to 6 modules that can be connected in parallel at higher load currents.
