Dc2199a-a is an evaluation board used for DC/DC & AC/DC (off-line) SMPS (Switch Mode Power Supply). It is suitable for high efficiency power factor correction (PFC) applications and it can also realize fan speed control and high efficiency LED lighting. The design is based on the synchronous rectification technology with low input power and low current consumption.

The dc2199a-a evaluation board is made up of two parts: the primary side power device and the secondary side synchronous rectification circuit. The power device consists of high frequency active power switch, a Fault Tolerant input current limiter, a rectifier, a snubber diode, a resonant transformer, and a return winding. On the secondary side, a low side MOSFET and a N-channel MOSFET form a synchronous rectification circuit. This rectification circuit reduces power consumption by reducing the switching losses.

The dc2199a-a can operate up to a peak efficiency of 98%, and its output voltage is automatically adjusted from 0.7V to 400V with a 0-10V digital control signal. It also features an ultra-low startup voltage, adjustable switching frequency, and over tension protection. The evaluation board also provides a built-in protection circuit which prevents the mains supply from fast switching or dangerous over voltage and over temperature.
