The IPS1042GPBF is a fixed-frequency primary-side controller from Infineon. It is designed to provide a constant output for DC/DC converters, such as those used in industrial, automotive and consumer applications. The part features primary side sensing, which enables accurate output voltage control and allows for a simplified stage PCB, a reduced number of components, and smaller size. It provides a 1.5A maximum current with multiple adjustable protection features such as over-temperature protection (OTP), soft-start, over-current protection (OCP), voltage and current regulation and short-circuit protection (SCP). It also offers external loop compensation to provide optimized transient response times and minimize the design times. Additionally, the IC supports high efficiency with its Burst Mode operation, which enables auto-standby and burst-mode current reduction, allowing high efficiency even at very light load. The device has an operating temperature range of -40°C to +125°C, making it suitable for industrial as well as harsh environmental applications.
