Infineon Technologies IR3640MPBF is a single-phase, positive output, step-down DC-DC controller IC. This device is designed with a buck topology and features a transistor driver output. It operates within a supply voltage range of 4.5V to 5.5V and supports switching frequencies from 225kHz up to 1.65MHz, with a maximum duty cycle of 92%. The controller integrates essential control features including current limit, enable, frequency control, power good indication, sequencing, and soft start. It also supports clock synchronization and includes a synchronous rectifier for improved efficiency. Packaged in a 20-MLPQ (3x4) with an exposed pad, the IR3640MPBF is suitable for surface mount applications and operates across an industrial temperature range of -40°C to 125°C. This component finds application in power management solutions across various electronic systems.
