产品描述

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.

产品特性

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:
- 8-bit ADC with integrated reference
- Comparator Input/General Purpose Output
- Interrupt request output with multiple sources
PWI® 2.0 Open-Standard Interface
Power-On Reset (POR) open-drain output with delay
LM10503-1 with start-up sequence option
