RAA229621GNP#HA0

• Gate Driver IC from Renesas, RAA229621 Series
• Listed as 2 output, 8 Phase Configuration
• Surface-Mount QFN-40 Package
• Drives Power MOSFET Gates from Controller Logic Signals in Multiphase Switching Stages
• RoHS Compliant

The RAA229621GNP#HA0 is a gate driver IC from Renesas in the RAA229621 series, listed as a 2-output, 8-phase surface-mount device in a QFN-40 package. Gate drivers sit between a controller and the power MOSFETs of a switching converter, translating low-power logic signals into the current needed to charge and discharge gate capacitance quickly, which is what keeps switching losses low in multiphase power stages. The RAA229621GNP#HA0 is RoHS compliant.

Multiphase, multi-output gate driver devices are used in high-current point-of-load power delivery, most commonly the CPU, GPU, and memory rails on server, workstation, and networking motherboards where load current is split across many phases to spread heat and improve transient response. The two independent outputs let one device serve two separate rails from a single package. Buyers are typically server and computing motherboard OEMs and ODMs, power module manufacturers, and repair and refurbishment operations sourcing replacement power-stage components.
