LM10503 is an advanced EMU containing three configurable, high-efficiency bucks for supplying variable voltages to a diverse range of applications. The device is ideal for supporting ASIC and SOC designs which use voltage scaling for reducing power consumption.
The device is digitally controlled via the PWI® 2.0 open-standard interface. LM10503 operates cooperatively with a PowerWise® technology-compatible ASIC to optimize the supply voltage adaptively (AVS - Adaptive Voltage Scaling) over process and temperature variations. It also supports dynamic voltage-scaling (DVS) using frequency/voltage pairs from pre-characterized look-up tables.
Three high-efficiency programmable bucks:
Integrated FETs with low RDSON
Bucks operate at 120° phase to reduce the input current ripple and capacitor size
Input Under Voltage Lock-out
Enable pin and internal soft start
Current overload and thermal shutdown
4-Channel Multi-Function Port (MFP) that includes:
