National Semiconductor's LMZ10503/4 Simple Switcher power module is touted as a DC-DC solution capable of driving up to a 4A load with power conversion efficiency, output voltage accuracy, line and load regulation. The LMZ10503/4 is available in an package that is said to enhance thermal performance and allow for hand or machine soldering.

The LMZ10503/4 can accept an input voltage rail between 2.95V and 5.5V and deliver an adjustable 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 response time, while allowing the option to use ceramic and/or electrolytic output capacitors. Externally programmable soft-start capacitor facilitates controlled start-up. The LMZ10503/4 has the following features: lossless cycle-by-cycle peak current limit to protect for over current or short-circuit fault, thermal shutdown, input under-voltage lock-out, and pre-biased start-up.
