Schematics Description

AC Input Circuit & Differential Filter

There are three components in the section. The Fuse F1 protects against over-current conditions which occur when some main components fail.
The LF1 is a common mode chock for the common mode noise suppression filleting because each coil with large impedance.
The BD1 is a rectifier and converts alternating current & voltage into direct current & voltage. The C1, L2, C2, C3 & C10 are composted of the Pi filter for filtering the differential switching noise back to the AC source.

AP3302A PWM Controller

The AP3302A PWM controller U1 and Opto-Coupler U2 and Q1 are the power-converting core components. Connected to filtered output after the bridge circuit, the R13 & R16 resistor path will provide start-up voltage and current during starting up through Vcc (Pin 5). Subsequent VCC power will be provided by voltage feedback from middle-tapped auxiliary winding through two options, R12-D5 and R8-D2-Q3-D3, depending on the desired output voltage.
This design is to accommodate the required wide voltage range to support various protocols (including QC 4/USB PD Programmable Power Supply PPS), from 3V to 12V.
Based on feedback from the secondary side (Pin CATH of F75183 Decoder) to the primary side (FB pin of AP3302A) through Opto-coupler U2, AP3302A will switch ON and Off Q1 to regulate the desired voltage and current on the secondary side.
APR345 Synchronous Rectification (SR) MOSFET Driver
APR345 operates in DCM mode in this design and drives the Q2 MOSFET based on the secondary side transformer on/off duty cycle.
As the power loss with the APR345-controlled MOSFET Q2 is less than that with Schottky Diodes, the total efficiency can be improved.

F75183 QC4/4+ Decoder & Protection on /off P MOSFET and Interface to Power Devices

The few sets of important pins provide critical protocol decoding and regulation functions in F75183.

CC1 & CC2 (Pin 19, 20): CC1 & CC2 (Configuration Channel 1 & 2) are defined by USB PD spec to provide the channel communication link between power source and sink devices.
D+ & D- (Pin 25, 24): While defined under USB PD for data transfer only, D+ and D- are used in QC4+ to provide voltage information and backward compatibility with QC2.0 and QC3.0 devices.
Constant Voltage (CV): The CV is implemented by sensing VBUS voltage before Q4 P-Mosfet via the resistor divider ratio (R1 & R6) and comparing with the U5 TL432 internal reference voltage to generate a CV compensation signal through U1 photo coupler to primary side PWM IC AP3302A FB pin & tune the duty cycle time for maintaining desired Vbus voltage. This voltage ratio point also is connected to with F75183 decoder IC FBD pin (pin 7), through the FBD pin the output voltages can be adjusted by firmware programming to satisfy the PD or QC devices that need the different voltage requirements.
Constant Current (CC): The CC mode is implemented by sensing across current sense resistor (R14=20mohm) voltage and feeds it into F75183 inner current sense amplifier, and then comparing with internal set programmable reference voltage to generate a current limited compensation signal and send it to primary side PWM AP3302A controller through FBD pin, U5 TL432 and U1 photo coupler.
EN_VBUS (Pin 14) to PMOSFET Gate: The pin is used to turn on/off the Vbus load switch (Q4 & Q5) to enable/disable voltage output to the Vbus.
- Two back-to-back MOSFETs (Q4 & Q5) are required to prevent reverse current from the attached battery source.

Quick Start Guide Before Connection

Before starting the QC4/4+ 27W EVB test, the end user needs to prepare the following tools and manuals.
- For details, please contact the Fintek local agent for further information (http://www.fintek.com.tw/index.php/2014-08-04-00-48-50/contactus-en).
- Test Tool: F75183 (Fintek’s Qualcomm Quick Charge 4/4+ Test Tool)
- Manual: F75183_QC4.0/4.0+ Test Tool_User Guide_V1.0
Prepare a certified three-foot Type-C cable and a Standard-A to Micro-B Cable.
The Standard-A to Micro-B cable should be connected to the Test Tool’s Micro-B receptacle & Adapter Standard-A receptacle respectively.
Connect the test tool input to the Micro-B power supply output.
A type-C cable for the connection between the Test Tool and 27W Adapter Type-C receptacles.
Connect the 27W Adapter input to the AC power supply output.
Ensure that the AC source is switched OFF or disconnected before the connection steps.
