| Part Number | LD5523T |
| Manufacturer | Leadtrend |
| Description | The LD5523T is built in a multi-mode PWM controller. 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 frequency swapping fun. |
| Features |
Secondary-side feedback control with quasi-resonant + CCM operation Low Startup Current (<1A) Ultra-low operating current at light load Cycle-by-Cycle Current Limit Green Mode Control UVLO (Under Voltage Lockout) LEB (Leading-Edge Blanking) on CS Pin VCC OVP (Over Voltage Protection) Adj. OVP (Over Voltage Protection) on FB pin. Adj. UVP (Under Voltage Protection) on FB pin. OLP (Over Load Protection) Internal OTP (Over Temperature Protection) Applications Switching AC/DC Adaptor Open Frame Switching Power Supply Typical Application Leadtrend Technology Corporati. |
