The ADP1074 is a current mode, fixed frequency, active clamp, synchronous forward controller designed for isolated dc to dc power supplies. Analog Devices proprietary iCouplers® are integrated in the ADP1074 to eliminate the bulky signal transformers and optocouplers that transmit signals over the isolation boundary. Integrating the iCouplers reduces system design complexity, cost, and component count and improves overall system reliability. With the integrated isolators and metal-oxide semiconductor field effect transistor (MOSFET) drivers on both the primary and the secondary side, the ADP1074 offers a compact system level design and yields a higher efficiency than a non-synchronous forward converter at heavy loads.

The primary side pins provide functions for programming the switching frequency, maximum duty cycle, external frequency synchronization, and slope compensation.

The secondary side pins provide functions for differential output voltage sensing, overvoltage, power good, tracking, and programmable light load mode setting.

The feedback signal and timing of synchronous rectifier pulse-width modulations (PWMs) are transmitted from primary to secondary or from secondary to primary sides through the iCouplers using a proprietary transmission scheme.

The ADP1074 also offers features such as input current protection, undervoltage lockout (UVLO), precision enable with adjustable hysteresis, overtemperature protection (OTP), and power saving light load mode (LLM).

Applications

  • Isolated dc-to-dc power conversion
  • Intermediate bus voltage generation
  • Telecom, industrial
  • Base station and antenna RF power
  • Small cell
    • PoE powered device
  • Enterprise switches/routers
  • Core/edge/metro/optical routing
  • Power modules

Product Detail

The ADP1074-EVALZ evaluation board allows users to evaluate the ADP1074 in a power supply application.

The evaluation board can deliver a rated current of 6 A in steady state and 8 A peak that is thermally limited for an input voltage range of 36 V dc to 60 V.

Multiple test points allow easy access to all critical nodes and pins.

Full data on the ADP1074 is available in the ADP1074 data sheet, which should be consulted in conjunction with UG-1115 when using the evaluation board.
