13DS1-05S05NNL Présentation
An isolated DC/DC converter is a power conversion module that transfers energy across a magnetic (transformer-based) barrier so that the output ground is galvanically isolated from the input ground. In the power-management hierarchy it sits between board-level regulators and point-of-load circuits, and is commonly used to break ground loops, create floating rails, or generate isolated secondary supplies from a single primary rail. Unregulated isolated converters of this class use an open-loop push-pull topology with a fixed switching frequency, so the output voltage tracks the turns ratio and varies slightly with load and input voltage.
Key features of the 13DS1-05S05NNL include the 1 W rated output power in a miniature surface-mount body, 5 V nominal input accepting 4.5 V to 5.5 V, a 5 V single output rated at 200 mA, and 10-pin SMD construction that supports automated reflow assembly. The RoHS-compliant construction suits commercial and industrial-grade designs. Because the converter is unregulated, output accuracy and ripple are specified per the manufacturer datasheet and should be verified for the actual load range.
Typical applications include isolated RS-485/RS-232 transceiver power supplies, isolated CAN bus nodes, ground-loop elimination in industrial measurement equipment, and floating gate-driver or analog rails in mixed-signal systems.
Design consideration: as an unregulated converter, the output voltage rises at light load; adding a post-ripple LDO or ensuring a minimum load will stabilize the rail.

Applications typiques
13DS1-05S05NNL convient pour 6 applications: Isolated RS-485 Field Bus Nodes, Isolated CAN Bus Interfaces, Floating Analog and Sensor Rails, Isolated Gate-Driver Bias Supplies, Isolated Serial and USB Port Protection, Medical and Test Instrumentation Floating Domains.
Isolated RS-485 Field Bus Nodes
Industrial RS-485 networks frequently span long cable runs and multiple equipment grounds, creating ground-loop currents that corrupt differential signaling. The 13DS1-05S05NNL breaks this loop by powering the isolated side of transceivers such as the ADM2582E or MAX14930-based isolators from its 1 W, 5 V, 200 mA galvanically isolated output. The 4.5 V to 5.5 V input connects directly to the controller-side 5 V rail without additional regulation. Because the module is unregulated, the isolated rail rises at light load; a low-dropout post-regulator or zener clamp keeps the transceiver supply within its absolute maximum. Placement near the transceiver with a 10 uF output capacitor minimizes the isolated-domain loop area and improves EMC performance on the bus.

Isolated CAN Bus Interfaces
CAN nodes in vehicles and factory automation need the physical-layer side isolated from the logic core to survive transients and ground potential differences. The 13DS1-05S05NNL supplies the isolated 5 V rail for digital isolator plus CAN-transceiver combinations (for example ISO1050 with an isolator, or ADM3053-class transceivers). Its 200 mA output covers typical CAN transceiver consumption of 40-70 mA with margin for bus fault conditions. The SMD-10P 15.2 x 8 mm body keeps the isolation barrier routing straightforward on a two-layer board. Designers should note the unregulated output's light-load rise and provide a minimum load or local clamp so the CAN transceiver stays within its 5 V plus 10 percent supply window under idle bus conditions.
Recommandé
Floating Analog and Sensor Rails
Precision analog front ends, shunt-based current sensors, and thermocouple interfaces benefit from a floating supply that eliminates ground-loop error. The 13DS1-05S05NNL generates an isolated 5 V domain from the main controller rail at up to 200 mA, enough for an instrumentation amplifier stage plus an ADC reference buffer. Because it is transformer-coupled and unregulated, switching-frequency ripple appears on the isolated rail; an LC filter (for example 10 uH plus 22 uF) followed by a low-noise LDO reduces ripple to levels acceptable for millivolt-resolution measurements. The module's isolation barrier also allows the sensor common-mode potential to float hundreds of volts from system ground, within the isolation rating stated in the YDS datasheet.
Recommandé
Isolated Gate-Driver Bias Supplies
Half-bridge and motor-drive topologies require a floating bias rail for the high-side gate driver referenced to the switching node. The 13DS1-05S05NNL provides a convenient 5 V isolated bias that, fed into a gate-driver with an internal regulator or through a small bootstrap arrangement, drives the high-side switch without an auxiliary winding on the power transformer. Its 200 mA capacity supports gate-charge currents of mid-size MOSFETs switching at tens of kilohertz; estimated gate-drive average current equals Qg times fsw, so verify the budget before selection. Local 1 uF and 10 uF decoupling right at the driver VDD pin handles the pulsed gate-charge demand of the unregulated converter output.
Recommandé
Isolated Serial and USB Port Protection
Equipment with externally accessible serial (RS-232/RS-485) or industrial USB-style ports must isolate logic ground from field wiring to prevent damage from surges and ground potential shifts. The 13DS1-05S05NNL powers the isolated-side logic of optocoupler- or digital-isolator-based port interfaces from its 1 W isolated output, while the 5 V input side connects to the internal logic supply. The 15.2 x 8 mm SMD-10P package fits the typical spacing between port connector and isolation barrier on industrial I/O boards. Keep the isolation gap under and around the module free of traces and respect the creepage and clearance dimensions in the datasheet drawing to preserve the isolation rating in polluted industrial environments.
Recommandé
Medical and Test Instrumentation Floating Domains
Bench instruments, data loggers, and patient-adjacent monitoring equipment use isolated power domains to separate measurement circuitry from the host system ground, improving safety and measurement fidelity. The 13DS1-05S05NNL supplies a 5 V, 200 mA isolated rail for front-end amplifiers, isolated communication links, and relay-control logic in these instruments. Its unregulated nature is acceptable where the downstream load is constant, or where an LDO follows the module for a precision rail. For any patient-connected application, the isolation voltage, creepage, and clearance from the YDS datasheet must be reviewed against the applicable medical safety standard by the responsible compliance engineer - this module is a general-purpose industrial-class component, not a certified medical power supply.

Notes de conception
Because the 13DS1-05S05NNL is unregulated, its 5 V output tracks the input and rises noticeably at light load. Estimated behavior for this class: with a 5.5 V input and near-zero load, the output can exceed 5.5 V, while at 200 mA full load with a 4.5 V input it can fall toward 4.5 V. Verify the load/regulation curves in the YDS datasheet across your actual input and load range. If the load requires a tight 5 V plus or minus 5 percent rail, add a low-dropout post-regulator or guarantee a minimum load of roughly 10-20 percent of rated current.
Place a 10 uF ceramic capacitor on the primary input and a 10 uF plus 1 uF pair on the isolated output, each within a few millimeters of the module pins. Keep the isolation barrier region beneath and around the SMD-10P body completely free of copper and traces so the internal creepage and clearance are preserved on the finished PCB. Route the isolated-side ground as its own island connected only through the module, and never run non-isolated signals across the barrier gap - route them around it or through a rated isolator.
The open-loop push-pull topology switches at a fixed frequency set by the internal oscillator, and the transformer coupling can radiate at the switching fundamental and its harmonics. Estimated mitigation: a common-mode choke or ferrite bead on the primary input, plus an LC filter (10 uH, 22 uF) on the output, typically reduces conducted ripple to tens of millivolts. Keep the module away from sensitive analog nodes and magnetically sensitive components, since the transformer's leakage flux falls off quickly with distance but can still induce noise in nearby high-impedance loops.
