TG110-E050N5LF is a high-performance isolated DC-DC converter module

The TG110-E050N5LF is a high-performance isolated DC-DC converter module designed for applications requiring stable, isolated low-voltage power. Manufactured by Recom Power (a leading provider of power conversion solutions), it integrates all necessary components (transformers, MOSFETs, controllers, and protection circuits) into a compact package, delivering reliable isolated power with minimal external components. Below is a detailed breakdown of its core functions and typical applications:

As an isolated converter, it provides galvanic isolation between the input (primary side) and output (secondary side), with an isolation voltage rating of 1.5kV DC (reinforced isolation). This critical feature prevents direct current flow between circuits, protecting sensitive downstream components from high input voltages, reducing ground loop interference, and ensuring compliance with safety standards (e.g., IEC 60950-1, IEC 62368-1).

• Input Voltage (VIN): Fixed at 5V DC, making it compatible with standard low-voltage power sources such as USB supplies, linear regulators, or other 5V DC-DC converters.
• Output Voltage (VOUT): Fixed at 5V DC, delivering a continuous output current of 0.2A (5V × 0.2A = 1W total output power). The output voltage tolerance is typically ±3% under full load and nominal input, ensuring stable power for precision circuits.

Leveraging advanced switching topology and integrated component optimization, the module achieves conversion efficiency up to 82% (typical at 5V input, 5V output, full load). High efficiency minimizes heat generation, eliminating the need for heat sinks even in enclosed environments. Additionally, it features low no-load power consumption (typically <0.1W), making it suitable for battery-powered or energy-efficient systems.

Housed in a ultra-compact SIP-7 (Single In-Line Package) with dimensions of 10.16mm × 8.76mm × 6.20mm, the module is ideal for space-constrained designs (e.g., compact industrial sensors, portable devices, or densely populated PCBs). The surface-mount form factor enables automated assembly, reducing manufacturing costs and improving production consistency.

To enhance system reliability and safety, the TG110-E050N5LF integrates multiple protection features:

• Over-Current Protection (OCP): Limits the output current to a safe threshold (typically ~120-150% of rated current) to prevent damage to the module and downstream loads.
• Over-Voltage Protection (OVP): Triggers shutdown or clamping if the output voltage exceeds a predefined limit (typically ~120% of nominal output), safeguarding sensitive components like microcontrollers (MCUs) or analog sensors.
• Short-Circuit Protection (SCP): Withstands direct short circuits at the output, either via auto-recovery (resuming operation when the short is removed) or latch-off (requiring a power cycle), depending on the variant.
• Thermal Shutdown (TSD): Disables the module if the internal temperature exceeds ~125°C (junction), preventing overheating and permanent damage.

• Wide Operating Temperature Range: Operates reliably from -40°C to +85°C (ambient), making it suitable for harsh environments such as industrial sites, outdoor equipment, or automotive auxiliary systems.
• Low Output Ripple & Noise: The integrated filter components ensure low output ripple (<50mV peak-to-peak typical) and noise, which is critical for powering analog circuits (e.g., sensors, amplifiers) or digital circuits sensitive to voltage fluctuations (e.g., low-power MCUs).

• Industrial Sensors & Transmitters: Provides isolated 5V power to analog front-ends (AFEs) of temperature, pressure, or humidity sensors. Isolation eliminates ground loop noise that could corrupt sensor data, while the compact size fits into miniaturized sensor housings.
• Fieldbus Modules (e.g., RS485, CAN): Powers isolated communication transceivers. Galvanic isolation protects the module from voltage transients common in industrial bus systems, ensuring stable data transmission.
• PLC I/O Modules: Supplies isolated 5V to input/output channels of Programmable Logic Controllers (PLCs). Isolation prevents cross-talk between channels and protects the PLC’s core logic from external electrical disturbances.

• Smart Home Devices: Powers isolated circuits in smart thermostats, security cameras, or smart meters. The 5V input compatibility works with USB or wall adapters, and low no-load power consumption extends battery life in wireless devices.
• Portable Medical Gadgets: Provides isolated 5V to low-power medical devices like pulse oximeters or glucose meters. Reinforced isolation complies with medical safety standards (e.g., IEC 60601-1), protecting both the device and the user.
• Audio Equipment: Supplies power to isolated preamplifiers or audio interfaces. Low output noise ensures clean audio signals, while isolation eliminates hum caused by ground loops.

• Low-Power Radio Modules: Powers isolated RF transceivers in wireless sensor networks (WSNs) or IoT nodes. Isolation shields the radio circuitry from input voltage fluctuations, improving signal integrity.
• Telecommunication Accessories: Provides isolated power to line interface circuits in small-scale telecom devices (e.g., VoIP adapters). The 1.5kV isolation rating meets telecom safety requirements for line-side isolation.

• Automotive Auxiliary Systems: Powers isolated sensor circuits (e.g., tire pressure monitoring system (TPMS) sensors) or low-voltage control modules. The wide operating temperature range tolerates extreme conditions in automotive environments, and isolation protects circuits from the car’s noisy 12V electrical system (when paired with a 5V front-end regulator).
• Marine Electronics: Supplies isolated 5V to navigation sensors or communication devices. Isolation prevents corrosion caused by ground potential differences in marine environments.
