The LMZ10505's SIMPLE SWITCHER ® power module is a complete, easy-to-use DC-DC solution capable of driving up to 5A loads with excellent power conversion efficiency, output voltage accuracy, line and load regulation. LMZ10505 is an innovative solution that enhances thermal properties and allows for manual or machine welding.
LMZ10505 can accept input voltage rails between 2.95V and 5.5V and provide adjustable and highly accurate output voltages as low as 0.8V. One megahertz fixed-frequency PWM switches provide a predictable EMI characteristic. Two external compensation components that can be adjusted to be set for the fastest response time, while allowing the option to use ceramic and/or electrolytic output capacitors. External programmable soft-start capacitors facilitate controlled start-up. LMZ10505 is a safe, reliable, and powerful solution that features lossless cycle-by-cycle peak current limiting to protect against overcurrent or short-circuit faults, thermal shutdown, input undervoltage lockout, and pre-bias start-up.
