EZ-PD™ PAG1: Power Adapter Generation 1

EZ-PD™ PAG1 is a 2-chip secondary-side controlled support quasi-resonance (QR) flyback converter using EZ-PD™ PAG1S CYPAS111. EZ-PD™ PAG1S integrates the internal error amplifier (EA) and a programmable ramp generator to determine the pulse width of the low-side PWM. The PWM driving signal is transferred from the secondary to the primary side through a pulse edge transformer (PET). EZ-PD™ PAG1P is designed to receive PWM driving signals from the secondary side and drive the primary switch. EZ-PD™ PAG1 is a highly programmable solution: EZ-PD™ PAG1S supports configurable digital valleys based on the line and load condition, dead-time, switching frequency to meet up different design requirements.

EZ-PD™ PAG1S CYPD3184 is a highly integrated USB PD and SR controller for a single port power adapter. It supports optocoupler feedback to the primary side PWM controller and supports DCM and QR of the flyback converter. EZ-PD™ PAG1S supports programmable SR with a volt-second integration feature that can optimize system performance with the primary side controller.

EZ-PD™ PAG1 is a highly integrated 2-chip solution including PWM, SR, PD controller, all necessary protection circuitry, primary low side, SR, and VBUS FET drivers which allows significant savings in terms of BOM and board area. It comes with a certified USB-PD stack and supports field upgrades with free and fully compliant firmware. Its high degree of programmability makes EZ-PD™ PAG1 a flexible solution that can be easily tuned to customers' needs. The programming can be done using the included configuration utilities: EZ-PD™ configuration utility and PSoC™ programmer. Additionally, customers can benefit from the variety of ready-to-download reference designs to speed up their development cycles and thus reduce the time-to-market.
