The Delphi DNL series is the latest product developed by Delta Electronics, Inc. It is a non-isolated point of load DC/DC power module with an input voltage range of 8.3~14V and an output voltage range of 0.75V~5.0V. The maximum output current is 16A. The product is available in a surface mount or SIP package and has outstanding electrical and thermal performance and extremely high reliability.
The DNL family of DC/DC power modules from Delta Electronics offers a compact, non‑isolated solution for point‑of‑load applications. Input voltage ranges from 8.3 V to 14 V, while the output can be trimmed to any voltage between 0.75 V and 5 V and deliver up to 16 A.
Key features include up to 92 % efficiency at 12 V input, remote on/off control with both positive and negative logic, remote‑sense capability, over‑current and over‑temperature protection, and a standard SIP or SMD package for easy board integration.

The DNL module can reach up to 92 % efficiency at 12 V input with a 3.3 V/16 A output.
Both positive and negative on/off logic are supported; positive logic turns the module on with a high signal, while negative logic turns it on with a low signal.
The turn‑on threshold is 7.9 V and the turn‑off threshold is 7.8 V.
