The ADP1031 is a high performance, isolated micropowermanagement unit (PMU) that combines an isolated flybackdc-to-dc regulator, an inverting dc-to-dc regulator, and abuck dc-to-dc regulator, providing three isolated power rails.Additionally, the ADP1031 contains four, high speed, serialperipheral interface (SPI) isolation channels and three general-purpose isolators for channel to channel applications where lowpower dissipation and small solution size is required.
Operating over an input voltage range of +4.5 V to +60 V, theADP1031 generates isolated output voltages of +6 V to +28 V(adjustable version) or+ 21 V and +24 V (fixed versions) forVOUT1, factory programmable voltages of +5.15 V, +5.0 V, or+3.3 V for VOUT2, and an adjustable output voltages of −24 V to−5 V for VOUT3.
By default, the ADP1031 flyback regulator operates at a 250 kHzswitching frequency and the buck and inverting regulators operateat 125 kHz. All three regulators are phase shifted relative to eachother to reduce electromagnetic interference (EMI). The ADP1031can be driven by an external oscillator in the range of 350 kHzto 750 kHz to ease noise filtering in sensitive applications.
The digital isolators integrated in the ADP1031 use AnalogDevices, Inc., iCoupler® chip scale transformer technology,optimized for low power and low radiated emissions.
The ADP1031 is available in a 9 mm × 7 mm, 41-lead LFCSP andis rated for a −40°C to +125°C operating junction temperaturerange.
