AI Technical Summary
Technical Problem
Existing PSE chips, which integrate high and low voltage components onto a single chip, suffer from problems such as numerous layers, large area, high cost, high design risk, and low success rate.
Method used
The PSE controller is divided into a low-voltage control chip and a high-voltage output chip, which are designed separately. The low-voltage control chip includes a low-voltage control circuit, and the high-voltage output chip includes a high-voltage drive circuit. The control and drive functions are realized through pin and circuit connection.
Benefits of technology
This reduces the complexity and design risk of a single chip, and decreases the number of layers, area, and cost.
