PMIC - AC DC Converters, Offline Switchers

LT1242IS8#PBF is a versatile power management integrated circuit (PMIC) for off-line switchers and AC/DC converters, designed to provide users with high performance and cost-effective solutions for their power management needs. This device is based on a current-mode single-ended primary inductance converter (SEPIC) architecture, using a sophisticated control architecture to provide superior functional performance for a large range of applications.The LT1242IS8#PBF utilizes a high-performance, 200V/100V N-Channel MOSFET to switch the AC power from the mains. This device is equipped with a high-current output FET with an over-current protection feature. The device includes two independently controlled outputs which enable the user to select one of two output voltages depending on their application’s requirements.The device features a low RDS(on) power MOSFET with high current capability, peak current and rise/fall times appropriate for a wide range of operating frequencies. This device also features an advanced current-mode control system that provides superior line stability and transient response. The current-mode control supports both current-mode and voltage-mode control, and the design is optimized to provide superior performance in both modes.The LT1242IS8#PBF is designed to provide superior efficiency and power savings in a wide range of applications. Its wide input range, low quiescent current and high efficiency enable high power density for operation up to 3kW. Its power factor correction (PFC) control is optimized for high efficiency, low input total harmonic distortion (THD), and minimized component count. The peak current limit protection for maximized device life is enabled by an internal auto-restart circuit.In addition, this device supports low output voltage range and synchronized switching, along with programmable switching frequency. This device supports I2C digital shut down, allowing the user to shut down the power safely when needed. Thermal protection is also featured, with an internal temperature sensor to detect over-temperature conditions and shut down the power if necessary.The LT1242IS8#PBF is a highly integrated PMIC, providing a powerful and efficient solution for a wide variety of applications. Its superior design, high efficiency, and low cost make it an ideal choice for customers looking to reduce component count and maximize power savings in their applications.
