SD8585S is a charger power chip

SD8585S Product Description:

SD8585S is a primary-side control switching power supply PSR with built-in high-voltage MOS transistor power switch. It adopts PFM modulation technology to provide an accurate constant voltage/constant current (VC/CC) control loop with very high stability and average efficiency.

Using SD8585S to design the system, no optocoupler is needed, secondary feedback control, loop compensation can be omitted, the circuit can be simplified, and the system cost can be reduced.

SD8585S is suitable for 10-12W output power, built-in line loss compensation function and peak current compensation function.

The traditional charger solution has high cost and low performance, while using Silan Micro SD8585S charger IC, which has built-in line loss compensation and peak current compensation functions, provides precise constant voltage and constant current control loops, and has very high stability performance and average efficiency, without optocouplers and Y capacitors, greatly reducing cost and improving performance.

SD8585S is an off-line switching power supply integrated circuit with a high-end switching power supply controller with built-in line loss compensation and peak current compensation. By detecting the peak current of the primary coil of the transformer and the feedback voltage of the auxiliary coil, the output voltage and current of the system are controlled to achieve the purpose of outputting constant voltage or constant current.

SD8585S has built-in high voltage MOS power switch, suitable for output power 10~12W charger, adapter, standby power supply. SOP7 package.

SD8585S control chip internal block diagram SD8585S includes undervoltage lockout, overvoltage protection, peak current detection, overtemperature protection, leading edge blanking, constant current, constant voltage control, open loop protection, cycle-by-cycle current limiting, peak current compensation, etc. functional circuit.
