External/Internal DC DC Converters

LMZ10505EXTTZ/NOPB Description

The LMZ10505EXTTZ/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments' SIMPLE SWITCHER® series, designed for compact, high-performance power management solutions. This 5A output module operates within an input voltage range of 2.95V to 5.5V, delivering an adjustable output voltage from 0.8V to 5V with an exceptional 96% efficiency. Housed in a surface-mount package (10.2mm x 9.9mm x 4.6mm), it integrates critical components, reducing board space and simplifying design. The device is ROHS3 compliant, REACH unaffected, and suitable for commercial ITE applications, making it ideal for space-constrained, high-reliability systems.

LMZ10505EXTTZ/NOPB Features

• High Efficiency (96%): Minimizes power loss and thermal dissipation, enhancing system reliability.
• Wide Input Range (2.95V–5.5V): Supports diverse power sources, including Li-ion batteries and 3.3V/5V rails.
• 5A Output Current: Delivers robust power for demanding loads without external FETs.
• Integrated UVLO (Under-Voltage Lockout): Protects against low-input-voltage conditions.
• Enable Control (Active High): Allows precise power sequencing and shutdown.
• Compact Footprint (10.2mm x 9.9mm): Ideal for densely populated PCBs.
• MSL3 (168 Hours): Ensures moisture sensitivity compliance for extended storage.

LMZ10505EXTTZ/NOPB Applications

This converter excels in commercial ITE equipment, such as:

• FPGA/ASIC Power Supplies: Provides stable, high-current voltage rails for logic cores.
• Portable Devices: Efficiently powers battery-operated systems like handheld testers.
• Industrial Sensors: Supports low-noise, high-efficiency power delivery in harsh environments.
• Networking Hardware: Ideal for routers/switches requiring compact, high-current solutions.
  Its small size and high integration make it superior to discrete buck converters, reducing BOM cost and design complexity.
