LMZ10504: 4A SIMPLE SWITCHER? Power Module with 5.5V Maximum Input Voltage The LMZ10504 SIMPLE SWITCHER? power module is a complete, easy-to-use DC-DC solution capable of driving up to a 4A load with exceptional power conversion efficiency,output voltage accuracy, line and load regulation. The LMZ10504 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ10504 can accept an input voltage rail between 2.95V and 5.5V and deliver an adjustable and highly accurate output voltage as low as 0.8V. One megahertz fixed frequency PWM switching provides a predictable EMI characteristic.
Two external compensation components can be adjusted to set the fastest response time, while allowing the option to use ceramic and/or electrolytic output capacitors. Externally programmable soft-start capacitor facilitates controlled startup.
