Description

General part information

LMZ10503EXT Series

The LMZ10503EXT power module is a complete, easy-to-use, DC-DC solution capable of driving up to a 3-A 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 accepts an input voltage rail between 2.95 V and 5.5 V and delivers an adjustable and highly accurate output voltage as low as 0.8 V. 1-MHz 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 or electrolytic output capacitors. Externally programmable soft-start capacitor facilitates controlled start-up. The LMZ10503EXT is a reliable and robust solution with the following features: lossless cycle-by-cycle peak current limit to protect for over current or short-circuit fault, thermal shutdown, input undervoltage lockout, and prebiased start-up. The LMZ10503EXT is also fully-enabled for WEBENCH®and Power Designer tools.
