LM10504数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The LM10504 is an advanced PMU containing three configurable, high-efficiency buck regulators for supplying variable voltages. The device is ideal for supporting ASIC and SOC designs for solid-state and flash drives.
The LM10504 operates cooperatively with ASIC to optimize the supply voltage for low-power conditions and power saving modes through the SPI interface. It also supports a 250-mA LDO and a programmable interrupt comparator.
