Description
This is high-performance off-line PWM controller for low-power AC/DC chargers and power adapter.
The M5840 is a high-performance off-line PWM power switch used in low-power AC/DC battery chargers, power adapters, and LEDs. The constant voltage and constant current accuracy can be maintained within ±5% within the full voltage input range. The chip adopts the primary side feedback technology, so that the TL431 and optocoupler can be saved in the system application to reduce the cost.
Pinouts:
Features
1. Constant voltage and constant current accuracy up to 5%
2. Primary side control mode, no need for TL431 and optocoupler
3. Flyback Topology in Discontinuous Mode
4. Quasi-resonant switching mode reduces switching losses
5. Built-in leading edge blanking circuit (LEB)
6. Constant voltage and constant current control
Applications:
Suitable for small and medium power AC/DC off-line switching power supply
1. CC/CV battery charger
2. Mobile/cordless phone chargers
3. digital camera charger
4. PDA charger
5. Low power power adapter
