Schematics Description

AC Input Circuit & Differential Filter

The Fuse F1 protects against over-current conditions which occur when some main components fails. The CM1 are common mode chocks for the common mode noise suppression. The DB is a bridge rectifier which converts alternating current and voltage into direct current and voltage. The EC1, L2, EC2, EC3 are composed of the Pi filter for filtering the differential switching noise back to AC source.

AP3304A PWM Controller

• The AP3304A is a peak-current control, multi-mode CCM+QR PWM controller which is optimized for high performance, and cost effective offline flyback converters. The AP3304A provides Mini Size Package of SOT23-6 and achieve high-power density charger applications. At no load or light load, the AP3304A enters the burst mode to minimize standby power consumption.

APR34910 Synchronous Rectification (SR) Switcher

• As a high-performance solution, The APR34910 is a secondary-side combo IC combining an N-channel MOSFET and a driver circuit designed for synchronous rectification (SR). The APR34910 effectively reduces the secondary side rectifier power dissipation which works in
  QR/DCM/CCM operation.

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, 10mΩ, 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 and 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.

The 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.
