Infineon IR3550MTRPBF 60A Integrated PowIRstage Synchronous Buck Gate Driver

Shenzhen Mingjiada Electronics Co., Ltd, as a well-known professional supplier of electronic components distribution services at home and abroad, has long been specialising in all kinds of electronic components, including the Infineon IR3550MTRPBF Integrated PowIRstage Synchronous Buck Gate Driver. Designed for next-generation servers, storage and communications systems, this IR3550MTRPBF high-performance power device delivers maximum current and efficiency in the smallest size.

Product Description Of IR3550MTRPBF

IR3550MTRPBF integrated PowlRstage is a synchronous buck gate driver co-packed with a control MOSFET and a synchronous MOSFET with integrated Schottky diode. It is optimized internally for PCB layout, heat transfer and

driver/MOSFET timing. Custom designed gate driver and MOSFET combination enables higher efficiency at lower output voltages required by cutting edge CPU, GPU and DDR memory designs.

Up to 1.0MHz switching frequency enables high performance transient response, allowing miniaturization of output inductors, as well as input and output capacitors while maintaining industry leading efficiency. The IR3550MTRPBF's superior efficiency enables smallest size and lower solution cost. The IR3550MTRPBF PCB footprint is compatible with the IR3551 (50A) and the IR3553 (40A). 

Integrated current sense amplifier achieves superior current sense accuracy and signal to noise ratio vs. best-in-class controller based Inductor DCR sense methods.

IR3550MTRPBF incorporates the Body-Braking® feature which enables reduction of output capacitors. Synchronous diode emulation mode in the IR3550MTRPBF removes the zero-current detection burden from the PWM controller and increases system light-load efficiency.

IR3550MTRPBF is optimized specifically for CPU core power delivery in server applications. The ability to meet the stringent requirements of the server market also makes the IR3550MTRPBF ideally suited to powering GPU and DDR memory designs and other high current applications.
