15W 5V USB adapter
This is a 15 W (5 V-3 A) wide range mains USB power adapter solution based on the STCH03 current-mode quasi-resonant controller, which combines a high-performance, low voltage PWM controller chip with a 650 V HV start-up cell in the same package. The switching controller provides constant output current (CC) regulation through primary-sensing feedback.<p>This solution maintains accurate output current regulation without the need for a dedicated current reference IC or a current sensor, and provides a full set of protections, including output overvoltage (OVP) and undervoltage (UVP) protection, transformer saturation and secondary diode short protection, which considerably increases end-product safety and reliability.<p>The architecture of the solution is based on a single-ended QR Flyback converter consisting of the following stages: (i) an input stage with front-end AC rectifier, low cost EMI filter, fuse and NTC to ensure safe converter operation; (ii) an RCD Snubber network protects the Power MOSFET at turn-off by limiting the leakage inductance voltage spike and dissipating the corresponding energy; (iii) a power and control stage with STD7N80K5 N-channel 800V, 0.95Ω MDmesh K5 Power MOSFET in DPAK package, connected to the HF transformer and driven by the STCH03 PWM controller - constant voltage (CV) and constant current (CC) operation is achieved with minimum number of external components; (iv) an output stage intended to implement high efficiency secondary side rectification based on FERD20U50DJF 50V, 20A Field-Effect Rectifier Diode (FERD) in Power FLAT package and to feed the Primary PWM IC with output voltage feedback signal.<p>This high power density, high efficiency power supply solution is able to satisfy energy saving recommendations (EuCoC rev. 5 – Tier 2 and EPS of DOE USA), with low standby power (less than 15 mW at 230 VAC), compliance with EN55022-Class-B Conducted noise emissions and immunity compliance according to IEC61000.
