The STR3A152D is a versatile and efficient power Metrics IC (PMIC) from STMicroelectronics. It is designed to provide reliable and efficient power delivery to a variety of applications, including AC/DC converters, offline switchers, and AC-DC power supplies. The device offers a flexibility allowing it to be used in a broad range of applications.The STR3A152D has an integrated 600 V power MOSFET, enabling it to deliver up to 10 A of continuous output current, with a peak output current of 20A. The device also has an integrated low-noise high-accuracy current-sense circuit, allowing it to detect the current in the output, enabling it to provide protection against over-current conditions.The STR3A152D also has a comprehensive set of protection features, including over temperature protection and current limit protection. It also has an integrated high-voltage clamp, allowing it to survive input voltage transients without any external components.The device has two operating modes, the voltage mode and the current mode. In voltage mode, the device regulates the output voltage based on the feedback from a voltage divider connected to the output of the power supply. In current mode, the device regulates the output current based on the voltage on the current sense pin. This allows for greater system flexibility, as the output current can be adjusted to meet the needs of the system.The device also has an integrated frequency converter. This allows the device to be used in applications that require higher switching frequencies than standard application frequencies. This also allows the device to be used in high-speed designs, enabling more accurate timing and control of the output power.The STR3A152D is capable of operating from an input voltage of 8V to 32V, making it suitable for use in a wide range of applications. It is packaged in a SSOP16 surface mount package and is lead-free reflow compatible.In summary, the STR3A152D is an excellent choice for applications that require reliable and efficient power delivery, such as AC/DC converters, offline switchers, and AC-DC power supplies. With its wide operating range and integrated protection features, the STR3A152D is a great solution for these demanding applications.
