Shenzhen Meiyuxin Technology Co., Ltd. specializes in TI automotive products] LM26480QSQ-AA/NOPB supports externally configured dual 1.5A step-down DC/DC and dual 300mA linear regulators! ! !

Product Description:

The LM26480QSQ-AA/NOPB is an automotive-qualified multifunction power management unit (PMU) optimized for low-power digital applications. The device integrates two high-efficiency 1.5-A step-down DC/DC converters and two 300-mA linear regulators. The DC/DC buck converter offers typical efficiency of 96% for lowest power dissipation. The device provides soft-start, under-voltage lockout, current-overload protection, thermal-overload protection, and an internal power-on reset (POR) circuit that monitors the output voltage levels on buck converters 1 and 2.
