AC DC Desktop, Wall Adapters

DPD120005-P1P-SZ application field and working principle The DPD120005-P1P-SZ is a power adapter specially designed for desktop and wall applications. It has a wide input voltage range of 90V-264V and provides protected regulated power output of 12Vdc with 500mA rating for different applications such as automotive power converters and portable electronics. Its built-in protection includes overvoltage, overcurrent and short circuit.

The DPD120005-P1P-SZ operates in two basic modes:

• In its DC mode, it provides a regulated output voltage of 12Vdc and is capable of supplying currents up to 500mA.
• In its AC mode, it can provide a regulated output voltage up to 12Vac with a peak current of 300mA.

The DPD120005-P1P-SZ uses a Flyback topology. The input voltage is stepped down to a low voltage by a transformer through a rectifier circuit. In the Flyback topology, the transformer stores energy in its magnetic core when input voltage rises and releases the energy when input voltage declines. This provides a smooth regulation for output voltage even if the input voltage is unstable. The output voltage of the transformer is then rectified and regulated to the specified output value. A wide input range ensures it is suitable for use in both DC and AC mains systems.

To protect the circuit against over-voltage and over-current conditions, there is a thermal protection circuit built into the design. This protects the device from thermal over-voltage,short circuit and over-current events. To further protect against failure, the power adapter also has an integrated power factor correction (CCFL) feature. This helps to ensure that the power adapter can operate reliably in a wide variety of operating conditions.

The DPD120005-P1P-SZ is suitable for use in different applications such as automotive power converters, portable electronics, AC/DC converters, and other applications.

The DPD120005-P1P-SZ is an efficient and reliable power adapter that is designed to provide regulated, protected power output in different applications. It is easy to operate, provides a wide input range, and has built-in protection features for a safe and secure operation. This makes it an ideal choice for a wide variety of applications.
