PN8368 5V1.5A high-precision low-power power chip

There are power chips on every circuit board, no matter it is a linear power chip or a switching power chip, they all have losses. Generally speaking, the loss of a switching power chip is much smaller than that of a linear power chip. The purpose of the power management chip is to improve efficiency and reduce power consumption to achieve green environmental protection requirements. In order to maximize the performance of the electronic system, it is particularly important to choose the most suitable power management chip. Liwei Electronics recommends a low-power and high-efficiency switching power chip PN8368.

The switching power supply chip PN8368 is a quasi-resonant primary feedback AC/DC converter with ultra-low standby power consumption within 5-12W. It integrates an ultra-low standby power consumption quasi-resonant primary controller and a 650V high avalanche capability intelligent power MOSFET. The constant voltage control mode adopts a multi-mode control method, which reasonably combines the high performance, high precision and high efficiency of the chip. In the full voltage AC input range, the unique adaptive compensation patented technology is adopted, and the output over-power protection circuit has a high consistency. At the same time, the built-in line loss compensation circuit ensures a high output voltage accuracy.

Features of low power consumption and high efficiency power chip PN8368:
1. Built-in 650V high avalanche capability intelligent power MOSFET
2. Built-in high voltage startup circuit, less than 30mW no-load loss (230VAC)
3. Quasi-resonance and multi-mode technology are used to improve efficiency and meet the 6-level energy efficiency standard
4. CC/CV accuracy of ±5% over the full voltage input range
5. Primary side feedback can save optocoupler and TL431
6. Constant voltage, constant current, and output line compensation are externally adjustable
7. No additional compensation capacitor is required
8. No audio noise
9. Intelligent protection function
