Chapter 1 Summary
1.1 General Description
The 65W 70CC Dual Type C Ports PD3.0 PPS Evaluation Board (EVB4) is composed of four main controllers, DIODESTM AP33510, DIODESTM APR349, DIODESTM AP43771V and Canyon Semiconductor’s CY6572. The AP33510, a highly integrated Quasi- Resonant (QR) controller with direct Enhancement Gallium Nitride (E-GaN) driver integration, is optimally designed to meet ultra-low standby power and high power density (HPD) charger applications. The APR349, a secondary side Synchronous Rectification (SR) Controller, is adopted for efficiency optimization. The AP43771V, a PD3.0 PPS protocol controller, automatically manages the PD3.0 PPS attachment process for the attached Type C-equipped Device Under Charged (DUC) regulates the feedback information of the charger to fulfill voltage and current requirements from DUC. CY6572 is a synchronous buck controller. Communication through I2C between two AP43771V, two Ports can realize smart power sharing once two ports both insert. By adopting popular E-GaN FETs, the 65W 70CC EVB4 exemplifies high power density charger design with optimized system BOM to meet market trend.

3.4 Schematics Description
3.4.1 AC Input Circuit & Differential Filter
The Fuse F1 protects against overcurrent conditions which occur when some main components fails. The NF1 and NF2 are common mode chocks for the common mode noise suppression. The BD is a bridge rectifier which converts alternating current and voltage into direct current and voltage. The CE1~CE3, L1, CE4, CE5 are composed of the Pi filter for filtering the differential switching noise back to AC source.
3.4.2 AP33510 PWM Controller
AP33510, a highly integrated Quasi Resonant Flyback (QR) controller, integrates high-voltage start-up function through HV pin and X-Cap discharging function. It also integrates a VCC LDO circuit, which allows the LDO to regulate the wide range VCCL to an acceptable value. This makes the AP33510 an ideal candidate for wide range output voltage applications such as USB PD3.0 PPS. With embedded E-GaN drive, the AP33510 provides safely and accurately Gate signal to control switch Q1 (GaN FET) operations and achieve high-power density charger applications. At no load or light load, the AP33510 enters the burst mode to minimize standby power consumption.
3.4.3 APR349 Synchronous Rectification (SR) MOSFET Driver
As a high performance solution, the APR349 is a secondary side SR controller to effectively reduce the secondary side rectifier power dissipation which works in both QR/DCM/CCM operation.
3.4.4 AP43771V PD 3.0 Decoder Interface to CY6572 Sync Buck and Power Devices
Few important pins provide critical protocol decoding and regulation functions in AP43771V:

1. CC1 & CC2 (Pin 11, 10): CC1 & CC2 (Configuration Channel 1 & 2) are defined by USB Type-C spec to provide the channel communication link between power source and sink device.
2. Constant Voltage (CV): The CV is implemented by sensing VFB (pin 8) and comparing with internal reference voltage to generate a CV compensation signal on the OCDRV pin (pin 5). The output voltage is controlled by firmware through CC1/CC2 channel communication with the sink device.
3. Constant Current (CC): The CC is implemented by sensing the current sense resistor (RCS, 10m, 1%, Low TCR) and compared with internal programmable reference voltage. The output current is controlled by firmware through CC1/CC2 channel communication with the sink device.
4. OCDRV (Pin5) to CY6572 COMP (Pin 4): It is the key interface link from CC/CV loop on AP43771V to Sync Buck COMP Pin(COMP) to realize Output CC/CV control. OCDRV is connected to CY6572 Pin 4(COMP) for feedback desired information based on all sensed Vbus, Current sense and CC1 & CC2 signals for getting desired Vbus voltage & current.
5. PWR_EN (Pin2) to N-MOSFET Gate: The pin is used to turn on/off N-MOSFET (Q9) to enable/disable voltage output to the Vbus.
   3.4.5 Interface between Master and Slave Board Master and Slave boards build interface via I2C communication. AP43771V SDA & SDL (Pin 16, 17) are defined by I2C
   spec to provide the channel communication link between Master and Slave, such as plug in/out, power sharing info. etc.
