Description
The RS85A10 is a compact TLGA device measuring 4mm x 6mm, designed for use in Server and Telecom applications that require high efficiency and small size.
It is a monolithic half-bridge that includes internal power MOSFETs and gate drivers, enabling it to achieve a continuous output current of 45A over a wide input supply range of 2.5V to 7.5V. The integration of driver and MOSFETs ensures high efficiency by reducing parasitic inductance and optimizing dead time.
This device can operate from 100kHz to 4MHz with 5V input voltage. It is compatible with tri-state output controllers and includes a general-purpose current sense and temperature sense, meeting industry specifications.
Applications
- Server and Telecom Voltage Regulators
- Graphic Card Core Regulators
- Power Module
