illustrate

The LMZ10504's SIMPLE SWITCHER ® power module is a complete, easy-to-use DC-DC solution capable of driving up to 4A loads with excellent power conversion efficiency, output voltage accuracy, line, and load regulation. LMZ10504 is an innovative solution that enhances thermal properties and allows for manual or machine welding.

LMZ10504 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. LMZ10504 is a safe, reliable, and powerful solution that features lossless cycle-by-cycle peak current limiting to protect against pass-through current or short-circuit faults, thermal shutdown, input undervoltage lockout, and pre-bias start-up.
