S17+ hash board SY8120B1ABC High-efficiency synchronous step-down DC-DC converter capable of delivering 2A load current. Temperature range: -40°C to 85°C; the SY8120B1 operates over a wide input voltage range of 4.5V to 18V and integrates extremely low main and synchronous switches to minimize conduction losses. The SY8120B1 uses an instant PWM architecture for a fast transient response, suitable for high buck applications and high efficiency at light loads. Also. It operates at a pseudo-constant frequency of 500 kHz under heavy load conditions to minimize inductor and capacitor size.
