The LMZ12001 SIMPLE SWITCHER ® Power Module is an easy-to-use step-down DC-DC solution for driving with excellent power conversion efficiency, line and load regulation 1A load capability, and output accuracy. The LMZ12001 is an innovative package that improves thermal performance and welding robots or permits.
The LMZ12001 can accept 4.5V to 20V input voltage rails and offers adjustable output voltages as low as 0.8V and highly accurate. The LMZ12001 requires only three external resistors and four external capacitors to complete the power solution. The LMZ12001 is a reliable, rugged design with the following protection features: thermal shutdown, input undervoltage lockout, output overvoltage protection, short-circuit protection, output current limiting, and allows entry into the start-up of the pre-biased output. A single resistor regulates switching frequencies up to 1MHz.
