ADP1031Three-Channel, Isolated Micropower Management Unit with Seven Digital Isolators | Development Boards, Kits, Programmers | 7 | Active | The ADP1031 is a high performance, isolated micropower management unit (PMU) that combines an isolated flyback dc-to-dc regulator, an inverting dc-to-dc regulator, and a buck dc-to-dc regulator, providing three isolated power rails. Additionally, the ADP1031 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.Operating over an input voltage range of +4.5 V to +60 V, the ADP1031 generates isolated output voltages of +6 V to +28 V (adjustable version) or+ 21 V and +24 V (fixed versions) for VOUT1, 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 kHz switching frequency and the buck and inverting regulators operate at 125 kHz. All three regulators are phase shifted relative to each other to reduce electromagnetic interference (EMI). The ADP1031 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 ADP1031 use Analog Devices, 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 and is rated for a −40°C to +125°C operating junction temperature range.ApplicationsIndustrial automation and process controlInstrumentation and data acquisition systemsData and power isolation |

ADP1052Digital Controller for Isolated Power Supply with PMBus Interface | Power Supply Controllers, Monitors | 2 | Active | The ADP1052 is an advanced digital controller with a PMBus™interface targeting high density, high efficiency, dc-to-dc power conversion. This controller implements voltage mode control with high speed, input line feedforward for enhanced transient and improved noise performance. The ADP1052 has six programmable pulse-width modulation (PWM) outputs capable of controlling most high efficiency power supply topologies, with added control of synchronous rectification (SR). The device includes adaptive dead time compensation to improve efficiency over the load range, and programmable light load mode operation, combined with low power consumption, to reduce system standby power losses.The ADP1052 implements several features to enable a robust system of parallel and redundant operation for customers that require high availability or parallel connection. The device provides synchronization, reverse current protection, prebias startup, accurate current sharing between power supplies, and conditional overvoltage techniques to identify and safely shut down an erroneous power supply in parallel operation mode.The ADP1052 is based on flexible state machine architecture and is programmed using an intuitive GUI. The easy to use interface reduces design cycle time and results in a robust, hardware coded system loaded into the built-in EEPROM. The small size (4 mm × 4 mm) LFCSP package makes the ADP1052 ideal for ultracompact, isolated dc-to-dc power module or embedded power designs.APPLICATIONSHigh density isolated dc-to-dc power suppliesIntermediate bus convertersHigh availability parallel power systemsServer, storage, industrial, networking, and communications infrastructure |
