Infineon Technologies IR3531MTRPBF

Description
The IR3531 is a 4 1 phase dual output control IC that provides all the necessary control, communication, and protection for compact dual output power solutions up to 210W. It can be combined with either discrete IR3535 driver ICs and DirectFets™ or the IR35XX family of footprint compatible and scalable PowlRstages™ which integrate the MOSFETs and driver into the same package.
The IR3531 provides overall system control and current sharing while the Driver IC or power stages sense per-phase current locally and communicate it to the Control IC. The IR3531 has tri-state PWM outputs to allow diode emulation during light load events.
The IR3531 provides a high-performance transient solution through classic voltage mode control and non-linear transient solutions, Turbo and Body Braking™. Turbo™ automatically turns on all phases to minimize load turn-on transients while Body Braking automatically turns off the low-side MOSFET to help dissipate stored inductor energy at load turn-off.
