The pc2 200w pdqc 3c1a is a compact power delivery module designed for high efficiency in slim devices. Engineered around the 3c1A core architecture, it balances compact size with stable 200 watt output.
This guide explains how the module integrates with modern USB-C networks, what performance limits to expect, and how it compares to legacy bricks.
| Attribute | Value | Notes | Impact |
|---|---|---|---|
| Model | pc2 200w pdqc 3c1a | Internal code for the reference design | Used in schematics and BOM |
| Rated Power | 200 W | Sustained output within thermal limits | Suitable for 15–17 inch laptops |
| Protocol | USB-C PD QC 3.0 | Programmable voltage from 5 V to 20 V | Fast negotiation with host devices |
| Efficiency | Up to 92% | Measured at full load, 230 VAC inlet | Reduces heat and power waste |
| Thermal Design | Temperature-limited foldback | Throttles above 85°C ambient | Protects surrounding components |
Power Delivery Behavior of pc2 200w pdqc 3c1a
Under typical conditions, the pc2 200w pdqc 3c1a negot voltages between 7.6 V and 20 V depending on the downstream load. The module supports PPS and dual-channel charging, which helps reduce resistive losses in cables.
During transient peaks, such as when a laptop wakes from sleep, the controller maintains regulation within ±2%. This stability is critical for devices with dynamic power demands.
Efficiency and Thermal Performance
Load Efficiency Curves
Efficiency stays above 88% from 30% to 100% load. At 50% load, the module typically runs 3–5°C cooler than competitive 180 W reference designs.
Cooling Recommendations
For enclosures with limited airflow, a 1 mm thermal pad between the module and chassis reduces surface temperature by up to 7°C.
Compatibility with USB-C Ecosystem
The pc2 200w pdqc 3c1a is backward compatible with USB Power Delivery 2.0 and can coexist with legacy chargers in mixed networks. It correctly declines invalid PDOs, which prevents potential damage to host circuits.
Cable quality plays a significant role; certified emarked cables are recommended above 100 W to ensure proper configuration channel communication.
Design Integration Guidelines
Layout engineers should keep the switching node loop tight and place low ESR capacitors within 5 mm of the VIN and VOUT pins. Ground planes under the module improve RF shielding and reduce radiated emissions.
Firmware revision 2.3 and later add adaptive switching frequency, which lowers acoustic noise in thin devices by shifting energy above the audible range.
Deployment and Lifecycle Considerations
Suppliers typically quote long-term availability for the pc2 200w pdqc 3c1a based on JEDEC qualification levels. Units stored above 85% RH should be baked prior to reflow to avoid delamination.
- Verify USB-C PD contract at 20 V 10 A before field deployment
- Test EFT and surge immunity per IEC 61000-4-4
- Monitor junction temperature with thermal shutdown hysteresis at 15°C margin
- Plan firmware updates for efficiency and security patches
FAQ
Reader questions
Can I use pc2 200w pdqc 3c1a in a 13 inch ultrabook?
Yes, it is oversized for most 13 inch ultrabooks but provides ample headroom for peak loads and keeps the charger warm rather than the device.
Does this module support laptop charging while the battery is removed? Yes, it can sustain full 200 W output with the battery disconnected, provided the system adheres to USB-C PD contract specifications. Is it safe to pair with third-party USB-C cables?
Use cables that comply with USB-IF certification for power above 60 W to ensure proper negotiation and avoid overheating.
What should I do if the module shuts down under full load?
Check ambient temperature and verify that the heatsink is properly seated; reduce peak current limits or improve airflow if thermal foldback is triggered frequently.
