• Not connected location (NC): R30,R63,C65,C66,R68,R69,C70,C71 / 0603; D61 / SOD323; R23 / 0805
• Current sense resistor (R61) should use the Low TCR type resistor (Reference Type: SMF12M1FR010T “http://www.sartfuse.com”).

Schematics Description

1. Fuse, EMI Filter and Rectifier
   The Fuse F1 protects against over-current conditions which occur when some main components failed. The L2 is a common mode choke for the common mode noise suppression. The BD1 is a rectifier witch converts alternating current and voltage into direct current and voltage. The C2, L1, C3 are composed of the Pi filter for filtering the differential switching noise back to AC source.

2. AP39303 QUASI-RESONANT PWM SWITCHER
   AP39303 is a highly integrated power switcher with a built-in Quasi-Resonant (QR) PWM controller and a 700V high performance Power MOSFET. AP39303 has built-in high-voltage start-up function and provides an excellent green power solution. The AP39303 integrates a 120V VCC LDO circuitry and allows a wide voltage range of VCC_IN. This makes to be a good choice in wide output voltage range application such as PD and QC.

3. APR34709 SYNCHRONOUS RECTIFICATION SWITCHER
   APR34709 is a secondary side Combo IC, which combines an N-Channel MOSFET and a driver circuit designed for synchronous rectification (SR). The internal N-MOSFET is optimized for low gate change, low RDS(ON), fast switching speed and body diode reverse recovery performance. The synchronous rectification can effectively reduce the secondary side rectifier power dissipation and provide high performance solution. By sensing primary MOSFET drain-to-source voltage, APR34709 can output ideal drive signal with less external components.

AP43771 QC4/4+ and PD3.0 Decoder
The following pins provide critical protocol decoding and regulation functions in AP43771:

1. CC1 & CC2 (Pin 10, 11): CC1 & CC2 (Configuration Channel 1 & 2) are defined by USB PD spec to provide the channel communication link between power source and sink devices.
2. D+ & D- (Pin 12, 13): 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.
3. Constant Voltage (CV): The CV is implemented by sensing VCC (pin 3) via built-in resistor divider and compared with internal reference voltage. The output voltages can be adjusted by firmware programming.
4. Constant Current (CC): The CC is implemented by sensing the current sense resistor (R61, 10mΩ) and compared with internal programmable reference voltage. The output current can be adjusted by firmware programming.
5. Loop Compensation: C64, R67 & C65 form the voltage loop compensation circuit, and C66, R68 & C67 form the current loop compensation circuit.
6. OCDRV (Pin 5): It is the key interface link from secondary decoder (AP43771) to primary regulation circuit (AP39303). It is connected to Opto-coupler U4 Pin 2 cath for feedback information based on all sensed CC1 & CC2, D+ & D- voltage status for getting desired Vbus voltage & current.

7. PWR_EN (Pin 2) to N-MOSFET Gate: The pin is used to turn on and off Vbus load switch (Q61) to enable and disable  voltage output to the Vbus respectively.
