About

Secondary-side USB-C PD, SR, and PWM controller

EZ-PD™ PAG1S - CYPAS111 is a highly integrated USB PD, SR, and PWM secondary-side controller supporting quasi-resonant flyback converters for highly efficient SMPS. The PWM signals are sent to the primary-side counterpart EZ-PD™ PAG1P through PET (CYPET131). For USB PD, the controller offers a highly programmable flash-based solution to meet PD 3.1 specifications with SPR, PPS, and EPR support. EZ-PD™ PAG1S integrates the following: 21.5 V LDO, VBUS NFET gate driver, low-side current sense amplifier, low-side SR NFET gate driver with voltage doubler, and error amplifier. For fault protection, EZ-PD™ PAG1S supports VBUS OCP, SCP, OVP, UVP, OTP, and VBUS-CC short. EZ-PD™ PAG1S - CYPAS111 QR solution offers configurable digital valleys based on line and load conditions, dead times, and switching frequencies to meet different design requirements.

Secondary-side USB-C PD and SR controller

EZ-PD™ PAG1S – CYPD3184 is a highly integrated USB PD and SR controller for a single-port power adapter. For USB PD, the controller offers a highly programmable flash-based solution to meet PD 3.1 specifications with SPR and PPS support. For SR, EZ-PD™ PAG1S supports QR/DCM converters, voltage-second integrations to avoid false turn-ons, and switching frequencies up to 150 kHz. EZ-PD™ PAG1S integrates the following: 21.5 V LDO, VBUS NFET gate driver, low-side current sense amplifier, ADC, low-side SR NFET gate driver with voltage doubler, and error amplifier for optocoupler feedback. For fault protection, EZ-PD™ PAG1S supports VBUS OCP, SCP, OVP, UVP, OTP, and VBUS-CC short. EZ-PD™ PAG1 - CYPD3184 offers a highly programmable USB PD and SR controller to meet different customer design requirements and specifications.

Why choose EZ-PD™ PAG1

EZ-PD™ PAG1 is a highly integrated two-chip solution including PWM, SR, PD controller, all necessary protection circuitry, primary low-side SR, and VBUS FET drivers which allow 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. The controller's 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.
