| Part Number | LD5523K |
| Manufacturer | Leadtrend |
| Description | In order to enhance the efficiency performance, the LD5523K integrates the multi-mode PWM controller, which consists of Quasi-Resonant (QR) PWM control for light load condition and Continue Conduction Mode (CCM) for heavy load condition. Moreover, the QR controller not only gains the system performance, but also brings the worse EMI capability, while the fre. |
