Infineon TDA21590AUMA1, 1 DC-DC, DC-DC Converter 90A, 5.5 V, 1.5 MHz 42-Pin, PQFN

The Infineon Integrated power stage contains a low quiescent current synchronous buck gate driver IC. It is co packed with control and synchronous MOSFETs along with an active diode structure that achieves low Vsd similar to a schottky with very little reverse recovery charge. The package is optimized for PCB layout, heat transfer, driver and MOSFET control timing, and minimal switch node ringing when layout guidelines are followed. The paired gate driver and MOSFET combination enables higher efficiency at lower output voltages required by cutting edge CPU, GPU and DDR memory designs.

Operation up to 1.5 MHz
VDRV under voltage lockout
Bootstrap under voltage protection
