ANALOG DEVICES ADP1032ACPZ-1-R7 Power Management IC, 2 Outputs, 2 Step Down Converter, 60V, 5.15 Vout, -40 to 125 °C, LFCSP-EP-41

ADP1032ACPZ-1-R7 is a high performance, isolated micropower management unit (PMU) that combines an isolated flyback and a dc-to-dc regulator providing two isolated power rails. Additionally, this device contains four high speed serial peripheral interface (SPI) isolation channels and three general-purpose isolators for channel to channel applications where low power dissipation and small solution size is required. By default, the ADP1032 flyback regulator operates at a 250KHz switching frequency, and the buck regulator operates at 125KHz. The two regulators are phase shifted relative to each other to reduce electromagnetic interference (EMI). It can be driven by an external oscillator in the range of 350KHz to 750KHz to ease noise filtering in sensitive applications. It is used in applications such as industrial automation and process control, instrumentation and data acquisition systems, data and power isolation.
