 The L5961 is the most compact and complete power-management IC specifically designed for MOST* (media oriented system transport) automotive optical networks.
The L5961 replaces discrete component solutions, including all power supplies required for a MOST node (INIC/NIC controller supply, optical transmitter and receiver supplies). Moreover, the high current capability of this integrated DC/DC converter is suitable for driving a small application (no other supply needed for the MOST node).
The L5961 is intended to compose a chipset with SMSC’s MOST network processors (INIC/NIC), and offers customers an easy plug-and-play approach.
The L5961 significantly reduces system costs and also design time and efforts.
Power management is configurable through the I²C bus, includes a diagnostic transceiver and enables very low power consumption in standby, through the ultra-zero power mode. The L5961 is available in both PowerSO and PowerSSO package options.
