Overview
| Topology | Flyback Converter |
| Input voltage | 90-265 V |
| Output 1 | 12 V / 2 A |
| IC revision | DN05082D |
Description
This design note describes a 15 W, universal AC mains, isolated Quasi-Resonant flyback converter compatible with Qualcomm’s High Voltage Dedicated Charging Port Quick Charge 3.0 Class A specification. The converter provides adjustable output voltage in a range from 3.6 Vdc to 12 Vdc. It maintains maximum output power 15 W at full range of the voltage output and at same time it limits the maximum output current to 2.0 A. The design is targeted for smart phone and tablet charger applications. The charger design utilizes ON Semiconductor’s new NCP4371 Qualcomm Quick Charge 3.0 Controller, NCP1361E Quasi-Resonant Controller and NCP4305 Synchronous Rectification controller.
Features
- Universal AC Input Range (90–265 Vac).
- Input Filter for Conducted EMI Attenuation
- Very Low Standby and No-load Power Consumption
- Quasi-Resonant Current Mode Control with Valley Switching
- Valley Lockout Avoids Audible Noise at Valley Jumping Operation
- Secondary Synchronous Rectification Control for High Efficiency
- Qualcomm Protocol Controller Supports QC2.0 and QC3.0
- Output 5 V/2.00 A, 9 V/1.67 A and 12 V/1.25 A
- Highly Configurable Power and Current Limit Profiles
- Standby Power < 75 mW @ 5 V Output
- Support Output Capacitor Discharge Function while Portable Device is Unplugged or during Transition from Higher to Lower Output Voltage
- Smooth Output Voltage Transition
Typical applications
- Quick charge 3.0 / Cell phone and laptop charger
