Description
This design note describes a 36 watt, Type C interface PD3.0/QC3.0, universal AC input, constant voltage power supply intended for smart phone, PAD and NB adaptor supporting PD3.0 and QC3.0 protocol, where isolation from the AC mains is required, and low cost, high efficiency, and low standby power are essential. The featured power supply is a simple QR Flyback topology utilizing ON Semiconductor’s NCP1340 HF PWM controller, NCP43080 synchronous rectified controller and NCP4371 QC3.0 protocol controller combined Cypress’s CCG3 PD protocol controller. This Design Note provides the complete circuit schematic details and BOM for 36W Type C Interface PD3.0/QC3.0 adaptor solution which supports PD output (5V-9V/3A, 15V2.4A and 20V/1.8A), QC2.0 output (5V/3A, 9V/2.67A, 12V/2.67A) and QC3.0 output (4V-8V/3A, 8V-12V/2.67A). This design combined with NCP4371 and CCG3 to support QC3.0 and PD3.0, QC protocol is transferred by CCG3 and sent to NCP4371, PD protocol is transformed to QC3.0 protocol and sent to NCP4371 to change output voltage. NCP4371 provides QC protocol decode and CC/CV control. This design also proposed a dual auxiliary power supply solution that low voltage Vcc supplies to controller in low output and high voltage Vcc supplies to controller in high output also shut down the zener bias of high voltage regulator in order to increase the efficiency.
