LM10506中文资料三路降压 + LDO 电源管理 IC (PMIC)数据手册TI规格书

描述 Description

The LM10506 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 LM10506 operates cooperatively with ASIC to optimize the supply voltage for low-power conditions and Power Saving modes via the SPI interface. It also supports a 100-mA LDO and a programmable Interrupt Comparator.
