LM10504 - Triple Buck + LDO Power Management Unit - 无 - 电源管理多通道IC(PMIC)解决方案 - 德州仪器

产品描述

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 via the SPI interface. It also supports a 250 mA LDO and a programmable Interrupt Comparator.
