UNDGI3100
|
UNDGI3100 is a 100W-class USB-C PD compatible AC/DC adapter for I.C.T./AV equipment. It features USB-C (with cable) and supports PD/PPS/QC/Apple modes. It covers the standard USB PD profiles of 5V/9V/12V/15V/20V and supports power delivery up to 20V and 5A, making it suitable for selecting external power supplies during design, evaluation, and mass production of devices that rely on USB-C power delivery. In terms of safety standards, it complies with IEC 62368-1 and PSE (Appendix Table 8). For EMC, it conforms to FCC Part15-B, EN(CISPR)55032-B, VCCI-B, etc., and meets immunity requirements including EN55035 and EN61000-4 series (ESD/radiated RF/EFT/surge/conducted RF, etc.). The protection circuit is equipped with short circuit/over-voltage/over-current/over-temperature (optional) protection. Additionally, it adopts GaN-MOSFET technology, contributing to miniaturization and high efficiency. Regarding efficiency, it meets Energy Efficiency Level VI (ErP/DoE) and complies with EU 2019/1782, DOE 10 CFR part 429/430, and DOE VII Draft. With a standby power of 0.21W, it is a series easily considered for energy-saving applications. As with our other products, semi-custom support allows for adjustment to meet required specifications. Please consult us regarding optimal specifications for mass production (cable specifications, labeling, packaging, etc.). Product series name:UNDGI3100 |

Key Features
Compact, high-efficiency design using GaN-MOSFET
Uses next-generation GaN-MOSFET technology. Despite its 100W-class high power output, compact size and high efficiency are achieved, making it suitable even where space or heat dissipation is limited.
USB-C PD compatibility with multi-profile output
Compliant with USB Power Delivery standards, supporting voltage profiles of 5V / 9V / 12V / 15V / 20V. In particular, it supports up to 20V and 5A (100W) output to power high-demand devices.
Supports major fast charging standards
- PD (Power Delivery) – Ensures compatibility with a wide range of USB-C-powered devices
- PPS (Programmable Power Supply) – Allows fine control of voltage and current for efficient charging with reduced heat
- QC (Quick Charge) – Ensures strong compatibility with Qualcomm devices
- Apple mode – Provides optimal power for Apple products such as MacBooks
Capable of powering a wide range of devices compliant with the PD 100W standard, such as I.C.T. and AV equipment.
Compliance with safety and EMC standards
As an external power source that meets B2B adoption requirements, it complies with various safety and EMC standards.
| Item | Applicable Standards |
|---|---|
| Safety Standards | PSE (Annex Table 8), IEC 62368-1 |
| EMC Standards | FCC Part15-B, EN(CISPR)55032 Class B, VCCI-B etc. |
