3.3 Transformer Design Specification

45W USB PD 3.0 AP3108L+APR346+CY2311 Page 6 of 28 7-1-2018
Release 1.0 www.diodes.com

3.4 Schematics Description

3.4.1 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 failed. The LF1 & CX1 are common mode chock filter for the common mode noise suppression filleting because of the
each coil with large impedance. The DB1 is rectifier, and basically converts alternating current & voltage into direct current & voltage.

3.4.2 AP3108L PWM Controller

The AP3108L PWM controller U1 and Opto-Coupler U4 and Q1 are the power converting core components. Connected to filtered
output after bridge circuit, R3 & R4 resistor path will provide start-up voltage and current during starting up through HV (Pin 9).
Subsequent VCC power will be provided by voltage feedback from the auxiliary winding through R18-D5. This design is to
accommodate with the required wide voltage range to support various protocols (including USB PD Programmable Power Supply
PPS), from 5V to 20V.

Based on feedback of secondary side (Pin CATH of CY2311_16L Decoder) to primary side (FB pin of AP3108L) through Opto­coupler U4, AP3108L will switch ON and Off Q1 to regulate desired voltage and current on the secondary side.

3.4.3 APR346 Synchronous Rectification (SR) MOSFET Driver

The APR346 operates in CCM & DCM mode in this design under different load and drives the Q2 MOSFET based on the secondary
side transformer on‘ s duty cycle from its VET pin, but the turning off principle is different for DCM and CCM. At CCM mode: APR346
will turn off Q2 MOSFET when CCM pin voltage rises over threshold voltage VTH_CCM. And CCM pin voltage was coupled by
through Y-Cap from primary side turning on signal. Turning off principle for DCM: APR346 would turn off Q2 MOSFET when Drain­Source voltage rises over the turning off threshold voltage VTHOFF.
As the power loss with the APR346-controlled MOSFET Q2 is less than Schottky Diodes, the total efficiency can be improved.

3.4.4 CY2311_16L PD3.0+ 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 CY2311_16L:

1) CC1 & CC2 (Pin 7, 8): 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) Constant Voltage (CV): The CV is implemented by sensing VCC (pin 13) via resistor divider and comparing with internal
reference voltage to generate a CV compensation signal on the CATH pin (pin 16). There is a loop compensation circuit C13 &
R31 between Pin3 & Pin16, the fast voltage response can be obtained by adjusting their value. The output voltages can be
adjusted by firmware programming.

3) Over Current protection (OCP): The OCP is implemented by sensing by current sense resistor (R33, 10mΩ) and current sense
amplifier, then comparing with internal programmable reference voltage to generate a signal on CATH pin (pin 16).

4) CATH (Pin 16): It is the key interface link from secondary decoder (CY2311_16L) to primary regulation circuit (AP3108L). It
is connected to Opto-coupler U4A cath for feedback information based all sensed CC1 & CC2 voltage status for getting desired
Vbus voltage & current.

5) GATE Driver (Pin 12) to PMOSFET Gate: The pin is used to turn on/off Vbus load switch (Q4) to enable/disable voltage
output to the Vbus. An extra PMOSFET (Q4) is required to prevent reverse current from the attached battery source.
