BL8087 PMU with a Synchronous 1A Buck and a CMOS 500mA LDO DESCRIPTION The BL8087 is a power management unit (PMU), with 1 synchronous Buck and 1 CMOS lowdropout regulators that delivers a maximum current of 1A for Buck’s output and a maximum current of 0.5A for LDO’s output. The synchronous buck is a high-efficiency, DC-toDC step-down switching regulator, capable of delivering up to 1A of output current. The device operates from an input voltage range of 2.6V to 6V and provides an output voltage from 0.6V to VDD, making the buck ideal for low voltage power conversions. Running at a fixed frequency of 1.5MHz allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples.
