| Part Number | LD5523M1 |
| Manufacturer | Leadtrend |
| Description | In order to enhance the efficiency performance, the LD5523M1 integrates the multi-mode PWM controller, which consists of Quasi-Resonant (QR) PWM control for light load condition and peak load mode 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. |
| Features |
Low Startup Current (<1A) 0.26mA Ultra-low operating current at light load Current Mode Control with 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. OPP (Over Power Protection) External OTP (Over Temperature Protection) on CS Pin Internal OTP (Over Temperature Protection) SDSP (Secondary Diode Short Protection) Gate Source/Sink Capability: 190mA/-150mA @ output pin with 33nF capacitor. Applications Switching AC/DC Adapto. |
