- Bigger Battery
- Longer charging
•
Customer Pain :
• Long charging time
•
Customer’s Need :
• To well charge a 3000mAh battery in 1 HOUR around
3
How to Solve The Pain
•
•
•
Generally, output voltage increasing for higher power delivery is better
Therefore QCOM proposes QC2.0 for the pain and Mediatek proposes
PumpExpress
Briefing QC2.0 :
– Up to 60W (5V/9V/12V/20V) over standard micro-USB hardware
• Uses existing USB BC1.2 cables/ connectors
• Backwards compatible with 5V USB BC1.2
•
QC2.0’s Target :
–
To full charge a 3300mAh battery in ONE hour around
Conventional USB Charging
Quick Charging

New PWM---FAN501
•
Major Targets on FAN501 :
– CCM operation at high frequency for size reduction
• High Line @ 85kHz for efficiency & EMI
• Low Line @ 140kHz for transformer size reduction
– 85k/140kHz fixed frequency for easier dealing CMN interference to touch panel
– CCM operation to boost efficiency
– SD for OTP to save external OTP circuit
– FAN501MPX : with VSUVP (feasible for 3V UVLO charger design)
– FAN501AMPX : without VSUVP (feasible for general 2V UVLO USB charger design)
– 10mW standby power
– MLP4x3 package
– MP already

Frequency Operation – CV/CC regulation
• CV regulation : 85kHz/140kHz Fixed frequency operation & burst mode
- 140kHz operation @ low line allows deep CCM operation to reduce
conduction loss
- 85kHz operation @ high line reduces switching loss and better EMI
- Fixed frequency to help deal with CMN interference to touch panel
•CC regulation : frequency reduction with VO drop
- At low line, frequency reduction from 140kHz to 50kHz.
- At high line, frequency reduction from 85kHz to 30kHz.

VS OVP and Shunt-Down(SD) Protection
VS OVP
• VS OVP
–
VS pin monitors output voltage cycle by cycle through
auxiliary winding divider resistor
–
As VS>2.8V with successive 7 cycles de-bounce time , VS
OVP is triggered and controller enters latch mode
Shunt-Down
• Shunt-Down
- SD pin flows out one constant current 100µA independent on
temperature
- Usually NTC thermistor connects to this pin for external overtemperature-protection
- While SD pin voltage is less than 1.0V, SD function is triggered
and controller enters latch mode
