This document describes the features and characteristics of the LSM2 series single output, non-isolated selectable-output POL DC/DC converters. They are suitable for distributed bus architectures with input ranges of 5V and 12V, and maximum outputs of 6A, 10A, or 16A. They are DOSA compatible and have phased start up sequencing and tracking, extensive self-protection, etc.
The LSM2 Series are point‑of‑load (POL) DC/DC converters designed for distributed power architectures. They offer 5 V or 12 V wide input ranges and selectable single‑output voltages (3.3 V or 5 V) with up to 16 A of output current. Key features include phased start‑up sequencing, extensive self‑protection, remote sense for voltage drop compensation, and a compact SMT package that meets RoHS standards. The manual covers performance specifications, wiring, safety considerations, and application notes.
| Input Voltage Range | 8.3‑14 V (12 V nominal) or 2.4‑5.5 V (5 V nominal) |
|---|---|
| Nominal Output Voltage | 5 V for D12 models, 3.3 V for W3 models |
| Maximum Output Current | 6 A, 10 A or 16 A depending on model |
| Efficiency | up to 95.8 % |
| Switching Frequency | 315 kHz (6 A models) or 230 kHz (10 A/16 A models) |
The LSM2 converters accept 8.3‑14 V for the 12 V (D12) versions and 2.4‑5.5 V for the 5 V (W3) versions.
Remote sense provides point‑of‑use regulation by compensating voltage drops up to 10 % of the output voltage, improving accuracy for distributed wiring.
The 6 A version can deliver up to 6 A of continuous output current.
