About Non-Isolated PoL Modules

Point-of-Load (PoL) converters deliver regulated voltage directly to high-demand components like processors, ASICs, or FPGAs, minimizing power distribution losses. Non-isolated variants provide cost-effective solutions where input-output separation isn’t critical, offering superior efficiency in confined spaces.

These modules simplify power architecture by integrating controllers, MOSFETs, and inductors into single packages. They enable rapid design cycles for applications requiring precise voltage margining, dynamic scaling, and thermal management – especially valuable in dense PCB layouts common to server boards, networking gear, and industrial controllers.

FAQs

Q: Can this module generate positive voltages?
A: No, the PTN04050AAD exclusively produces negative output voltages from -3.3V to -15V.

Q: Is external compensation required?
A: No, this fully integrated solution requires no external compensation components.

Q: What’s the typical start-up time?
A: The module achieves regulated output within 20ms under full load conditions.

Q: Does it require heatsinking?
A: For continuous operation above 0.8A or ambient temperatures exceeding 65°C, TI recommends supplemental cooling.

Q: Why choose non-isolated converters?
A: They offer higher efficiency (>90% achievable), smaller footprints, and lower BOM costs versus isolated equivalents when safety isolation isn’t mandated.

Q: How do I confirm compatibility?
A: Consult the hosted datasheet on PCXCo.com for detailed load regulation graphs and stability criteria.
