The Si825x programmable digital power controller family provides closed-loop feedback control, system protection and power management functions for switch mode power systems and motor control applications.
The Si825x architecture combines a dedicated DSP-based control loop processor with an in-system programmable system management processor in a single package. This architecture guarantees the control loop is updated at 10 MHz, regardless of firmware size and complexity, for the fastest possible control response.
Firmware can change all control parameters on the fly (loop gain, compensation, timing, etc.) enabling the system to quickly and intelligently adapt to changing operating conditions such as lead transients. A low-cost development kit, which includes a complete real-time firmware kernel and turnkey digital power supply target board with intuitive, easy-to-use design tools, is available.
