LMZ10503EXT 3-A SIMPLE SWITCHER Power Module With 5.5-V Maximum Input Voltage  
for Demanding and Rugged Applications  
1 Features  
2 Applications  
1
•
•
Integrated Shielded Inductor  
•
Point-of-Load Conversions From 3.3-V and 5-V  
Rails  
Flexible Start-up Sequencing Using External Soft-  
Start, Tracking, and Precision Enable  
•
•
Space-Constrained Applications  
•
•
•
Protection Against In-Rush Currents and Faults  
Such as Input UVLO and Output Short-Circuit  
Noise-Sensitive Applications (Such as  
Transceiver, Medical)  
Single Exposed Pad and Standard Pinout for Easy  
Mounting and Manufacturing  
3 Description  
The LMZ10503EXT 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 LMZ10503EXT is  
available in an innovative package that enhances  
thermal performance and allows for hand or machine  
soldering.  
Pin-to-Pin Compatible With  
–
–
LMZ10504EXT (4-A/20-W Maximum)  
LMZ10505EXT (5-A/25-W Maximum)

–
15-W Maximum Total Output Power  
Up to 3-A Output Current  
The LMZ10503EXT 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. 1-MHz fixed-frequency PWM switching  
Input Voltage Range 2.95 V to 5.5 V  
Output Voltage Range 0.8 V to 5 V  
provides  
a predictable EMI characteristic. Two  
±1.63% Feedback Voltage Accuracy Over  
Temperature  
external compensation components can be adjusted  
to set the fastest response time, while allowing the  
option to use ceramic or electrolytic output capacitors.

Operates at High Ambient Temperatures  
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.
