The LSN2-T/30-D12 series DOSA-SIP, 30A POL DC/DC converters are an ideal regulation and supply element for distributed power and intermediate bus architectures. The converter is fully compatible with the Distributed-power Open Standards Alliance specification (www.dosapower.com). LSN2-T/30-D12 can power CPU’s, programmable logic and mixed voltage systems with little heat and low power consumption.
The LSN2‑T/30‑D12 Series are non‑isolated, point‑of‑load (POL) DC/DC converters designed for distributed power and intermediate‑bus architectures. They provide user‑selectable output voltages from 0.8 V to 5 V, a maximum output current of 30 A, and up to 150 W of power in a compact SIP package. Features include a fully synchronous buck topology, fast transient response (25 µs), high efficiency (up to 94 %), and a range of protection functions such as short‑circuit hiccup shutdown and input over‑/under‑voltage shutdown.
The datasheet lists detailed electrical specifications, ordering information, and technical notes on I/O filtering, remote sense, power‑good output, and thermal derating. It also covers safety considerations, recommended input fusing, and guidelines for power‑up sequencing and remote on/off control, helping designers integrate the device into mixed‑voltage systems with minimal external components.
| Output voltage range | 0.8‑5 Vdc |
|---|---|
| Maximum output current | 30 A |
| Input voltage range | 6‑14 Vdc |
| Maximum power | 150 W |
| Efficiency | up to 94 % |
| Operating temperature range | -40 °C to +85 °C |
The converters can deliver up to 30 A of output current.
It includes short‑circuit “hiccup” shutdown, output over‑voltage/over‑current protection, and input under‑ and over‑voltage shutdown.
The output voltage is selected with an external programming resistor or by applying a DC voltage to the trim pin.
The start‑up time is about 7 ms for the output to become regulated after power is applied.
