4 Circuit Description
4.1 Input EMI Filtering
Fuse F1 isolates the circuit and provides protection from component failure, and the
common mode choke L1 with capacitor C8 provides attenuation for EMI. Bridge rectifier
BR1 rectifies the AC line voltage and provides a full wave rectified DC across the filter
consisting of C2, L3, and C3. The inductor L3 and capacitors C2, C3 form a pi-filter. This
filter provides differential and common mode noise filtering. Thermistor RT1 limits the
inrush current when the power supply is connected to the input AC supply.
4.2 InnoSwitch-CP IC Primary
One end of the transformer primary is connected to the rectified DC bus; the other is
connected to the drain terminal of the MOSFET inside the InnoSwitch-CP IC (U1).
A low cost RCD clamp formed by diode D1, resistors R1 and R2, and capacitor C4 limits
the peak drain voltage of U1 at the instant of turn off of the MOSFET inside U1. The
clamp helps to dissipate the energy stored in the leakage reactance of transformer T1.
The IC is self-starting, using an internal high-voltage current source to charge the BPP
pin capacitor (C7) when AC is first applied. During normal operation the primary side
block is powered from an auxiliary winding on the transformer T1. Output of the auxiliary
(or bias) winding is rectified using diode D2 and filtered using capacitor C6. Resistor R4
limits the current being supplied to the BPP pin of the InnoSwitch-CP IC (U1). A linear
regulator comprising of resistor R3, BJT Q1 and Zener diode VR1 prevent any change in
current through R4. The RC network comprising of resistor R5 and capacitor C5 offer
damping to the high frequency ringing in the voltage across diode D2 which reduces
radiated EMI.
Output regulation is achieved using On/Off control, the number of enabled switching
cycles are adjusted based on the output load. At high load, most switching cycles are
enabled, and at light load or no-load most cycled are disabled or skipped. Once a cycle is
enabled, the MOSFET will remain on until the primary current ramps to the device
current limit for the specific operating state. There are four operating states (current
limits) arranged such that the frequency content of the primary current switching pattern
remains out of the audible range until at light load where the transformer flux density
and therefore audible noise generation is at a very low level.
Zener diode VR3 offers primary sensed output over voltage protection. In a flyback
converter, output of the auxiliary winding tracks the output voltage of the converter. In
case of over voltage at output of the converter, the auxiliary winding voltage increases
and causes breakdown of VR3 which then causes a current to flow into the BPP pin of
InnoSwitch-CP IC U1. If the current flowing into the BPP pin increases above the ISD

threshold which has a nominal value of 7.6 mA, the InnoSwitch-CP controller will latch
off and prevent any further increase in output voltage.
4.3 InnoSwitch-CP IC Secondary
The secondary side of the InnoSwitch-CP IC provides output voltage, output current
sensing and drive to a MOSFET providing synchronous rectification. The secondary of the
transformer is rectified by MOSFET Q2 and filtered by capacitors C10 and C11. High
frequency ringing during switching transients that would otherwise create radiated EMI is
reduced via a RC snubber, R6 and C9.
The gate of Q2 is turned on by secondary side controller inside IC U1, based on the
winding voltage sensed via resistor R10 and fed into the FWD pin of the IC.
In continuous conduction mode of operation, the MOSFET is turned off just prior to the
secondary side commanding a new switching cycle from the primary. In discontinuous
mode of operation, the power MOSFET is turned off when the voltage drop across the
MOSFET falls below a threshold of approximately 24 mV. Secondary side control of the
primary side power MOSFET avoids any possibility of cross conduction of the two
MOSFETs and provides extremely reliable synchronous rectification.
The secondary side of the IC is self-powered from either the secondary winding forward
voltage or the output voltage. Capacitor C13 connected to the BPS pin of InnoSwitch-CP
IC U1 provides decoupling for the internal circuitry.
During CC operation, when the output voltage falls, the device will power itself from the
secondary winding directly. During the on-time of the primary side power MOSFET, the
forward voltage that appears across the secondary winding is used to charge the
decoupling capacitor C13 via resistor R10 and an internal regulator. This allows output
current regulation to be maintained down to ~3.0 V. Below this level the unit enters
auto-restart until the output load is reduced.
Output current is sensed by monitoring the voltage drop across resistor R12 between the
IS and GND pins with a threshold of approximately 50 mV to reduce losses. Once the
internal current sense threshold is exceeded the device adjusts the number of switch
pulses to maintain a fixed output current.
Below the CC threshold, the device operates in constant voltage mode. Output voltage is
regulated so as to achieve a voltage of 1.2 V on the FB pin. Resistor R9 and capacitor
C12 form a phase lead network that ensure stable operation and minimize output voltage
overshoot and undershoot during transient load conditions. Capacitor C14 provides noise
filtering of the signal at the FB pin.

4.4 USB Type-C and PD Interface
In this design, CCG2 CYPD2134-24QXIT (U3) is the USB Type-C and PD controller.
Output of the InnoSwitch-CP powers the CCG2 device using a 3.3 V linear regulator U4.
Resistors R8 and R11 forms the feedback divider network to sense the output of
Innoswitch. Output voltage is changed to 9 V when sink requests for the same. To
change the output to 9V, pin-14 of IC U3 goes low and adds resistor R15 in parallel to
the bottom resistor of the feedback divider network.
USB-PD protocol is communicated over either CC1 or CC2 line depending on the
orientation in which type-C plug is connected.
P-MOSFETS Q10 and Q11 make the USB Type-C receptacle cold socket when no device is
attached to the charger as per the USB Type-C specification. VBUS_OUT is discharged via
resistor R34 by turning on the MOSFET Q13.

12.4 Output Ripple Measurements
12.4.1 Ripple Measurement Technique
For DC output ripple measurements, a modified oscilloscope test probe must be utilized
in order to reduce spurious signals due to pick-up. Details of the probe modification are
provided in the Figures below.
The 4987BA probe adapter is affixed with two capacitors tied in parallel across the probe
tip. The capacitors include one (1) 0.1 F/50 V ceramic type and one (1) 47 F/50 V
aluminum electrolytic. The aluminum electrolytic type capacitor is polarized, so proper
polarity across DC outputs must be maintained (see below).
