| Part Number | LD5523D2 |
| Manufacturer | Leadtrend |
| Description | In order to enhance the efficiency performance, the LD5523D2 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 gains the system performance, but also brings the worse EMI capability, especially at boundar. |
| Features |
PSR CCM+QR Multi-Mode Control. Frequency Swapping for better EMI performance Low Startup Current (<1.5A) Built-in load regulation compensation 65 kHz PWM switching frequency. Current mode control with cycle-by-cycle current limit UVLO (Under Voltage Lock Out) LEB (Leading-Edge Blanking) on CS pin VCC & FB Over Voltage Protection Adjustable Brown in/out on FB pin. External OTP (Over Temperature Protection) on CS Pin Internal OTP (Over Temperature Protection) Gate Source/Sink Capability: 40mA/-170mA @ output pin with 1nF capacitor. Applications Networking power suppl. |
