Description
The LD7531A is built-in with several functions, protection and EMI-improved solution in a SOT-26 / DIP-8 package. It takes less components counts or circuit space, especially ideal for those total solutions of low cost. The implemented functions include low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and internal slope compensation. And the LD7531A features more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent the circuit damage from the abnormal conditions.
Features
1. High-Voltage CMOS Process with Excellent ESD protection
2. Very Low Startup Current (<20μA)
3. Current Mode Control
4. Non-audible-noise Green Mode Control
5. UVLO (Under Voltage Lockout)
6. LEB (Leading-Edge Blanking) on CS Pin
7. Programmable Switching Frequency
Applications
1. Switching AC/DC Adaptor and Battery Charger
2. Open Frame Switching Power Supply
