Microchip Technology, Inc. Pwm Controller, I2C, 42V, Qfn-28; Input Voltage Microchip MCP19115T-E/MQ

The PWM Controller, part number 17X9130, is a digitally enhanced power analog synchronous low-side PWM controller designed for a wide input voltage range of 4.5V to 42V. It supports multiple topologies, including flyback, Ćuk, boost, and SEPIC configurations, making it versatile for various applications. The controller features both quasi-resonant and fixed-frequency operation modes, with a fixed switching frequency range from 31.25 kHz to 2.0 MHz. Key specifications include low quiescent current of 5 mA and sleep current of 30 µA, which contribute to energy efficiency. The device is equipped with low-side gate drivers capable of providing 5V and 10V gate drive outputs with sink/source currents of 0.5A and 1A, respectively. It also incorporates peak current mode control, differential remote output sense, and supports multiple output systems in master or slave configurations. The controller is AEC-Q100 qualified, ensuring reliability in automotive applications. Configurable parameters include input undervoltage and overvoltage lockout, primary current leading edge blanking, gate drive dead time, and slope compensation. Additionally, it features an integrated low-side differential current sense amplifier with ±5% current regulation and thermal shutdown for enhanced protection. This product is suitable for engineers looking for a robust and flexible PWM controller for their projects.
