The ADP1034 is high performance, isolated micropower management unit (PMU) that combines an isolated flyback dc-to-dc regu-lator, an inverting buck boost dc-to-dc regulator, and a buck dc-to-dc regulator, providing three isolated power rails. The ADP1034 includes 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 are required.

Operating over an input voltage range of 4.5 V to 60 V, the ADP1034 generates isolated output voltage ranges of 6 V to 28 V for VOUT1, −24 V to −2 V for VOUT3, and a factory-programmable voltage of 5 V for VOUT2. Additionally, a PPC_IN pin is provided for adjusting the VOUT1 setting on demand through a serial command that allows higher efficiency in system level applications.

By default, the ADP1034 flyback regulator operates at a 250 kHz switching frequency, and the buck and inverting regulators operate at 125 kHz. The ADP1034 can be driven by an external oscillator in the range of 350 kHz to 750 kHz to ease noise filtering in sensitive applications.

The digital isolators integrated in the ADP1034 use Analog Devices, Inc., iCoupler® chip scale transformer technology optimized for low power and low radiated emissions. The ADP1034 is available in a 9 mm × 7 mm, 41-lead lead frame chip scale package (LFCSP) and is rated for a −40°C to +125°C operating junction temperature range.

Product Detail

The ADP1034CP-1-EVALZ is a fully featured evaluation board that demonstrates the functionality of the ADP1034 dc-to-dc flyback regulator with programmable power control (PPC), buck and inverting buck-boost regulators, and the isolated data channels.

Users can evaluate ADP1034 device measurements, such as line regulation, load regulation, and efficiency with the evaluation board. The ADP1034CP-1-EVALZ board also assists in evaluating the functionality of the PPC and isolated digital channels. Device features including oscillator synchronization, soft start, sequencing, and slew rate control can be demonstrated on the evaluation board.

Full details about the ADP1034 are available in the ADP1034 data sheet, which must be consulted when using the ADP1034CP-1-EVALZ. Refer to the ADP1034 data sheet for more details about the dc‑to-dc converters and isolated data channels.
