MP173AGJ-Z

The MP173AGJ-Z is an offline switching controller designed for AC-DC conversion applications. It supports multiple topologies including boost, buck, buck-boost, and flyback, making it versatile for various power supply designs. The device operates with an input voltage range of 5.5V to 5.7V and can deliver up to 4W of power. It includes protection features such as open loop, overload, over-temperature, and short circuit protection, as well as a soft start control feature. The operating junction temperature range is -40°C to 125°C. The controller is non-isolated and does not have internal switches, requiring an external switching element. It is available in a SOT-23-5 Thin or TSOT-23-5 surface mount package, suitable for compact designs. This controller is ideal for applications requiring a flexible, low-power offline power supply. The multi-topology support allows it to be used in a wide range of converter configurations. The small TSOT-23-5 package enables space-constrained designs.
