Product Description

The LMZ10503 SIMPLE SWITCHER 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 LMZ10503 is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.
The LMZ10503 can accept an input voltage rail between 2.95 V and 5.5 V and can deliver an adjustable and highly accurate output voltage as low as 0.8 V. 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. The LMZ10503 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.
Integrated Shielded Inductor
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
Single Exposed Pad and Standard Pinout for Easy Mounting and Manufacturing
Pin-to-Pin Compatible With
LMZ10504 (4 A / 20 W Maximum)
LMZ10505 (5 A / 25 W Maximum)
Electrical Specifications
