Product Overview

The LMZ10503EXTEVAL/NOPB is an evaluation module for LMZ10503 simple switcher power module, which is complete, easy to use DC to DC solution capable of driving up to a 3A load with exceptional power conversion efficiency, output voltage accuracy, line and load regulation. The LMZ10503EXT is available in an innovative package that enhances thermal performance and allows for hand or machine soldering. The LMZ10503EXT 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 start up.
  • Flexible start up sequencing using external soft start, tracking, and precision enable
  • Protection against in rush currents and faults such as input UVLO and output short circuit
  • Operates at high ambient temperatures
  • High efficiency up to 96% reduces system heat generation
  • Low radiated emissions (EMI) complies with EN55022 class B standard
  • Low output voltage ripple of 10mV allows for powering noise sensitive transceiver and signalling ICs
  • Fast transient response for powering FPGAs and ASICs
  • 15W maximum total output power
  • Up to 3A output current
  • 0.8V to 5V output voltage range
