VIPer 12A and TOP246Y can pass more current than top243y, while other parameters are the same, so completion can be replaced and will be better. However, the breakdown damage of VIPer 12A is usually caused by high peak voltage, so check the reason, otherwise the above failure will still occur.
Extended data:
VIPer 12a adopts compact SO-8 or DIP-8, and integrates a dedicated current-mode PWM controller and a high-voltage power supply MOSFET, among which the MOSFET adopts a durable patented intelligent power supply technology, allowing the output current to flow vertically through the silicon wafer.
The VDD pin, which is responsible for providing control logic, has strong input voltage capability, which makes VIPer 12a especially suitable for wall-mounted adapters of battery chargers and standby power supplies for televisions and monitors.
