ROHM Semiconductor BD91xx Synchronous Buck Converter Integrated FETs

ROHM BD91xx Synchronous Buck Converter Integrated FETs are high-efficiency step-down switching regulators that are for the power supply designed to produce a low voltage including 1V from a 5/3.3V power supply line. These devices offer high efficiency with ROHM's original pulse skip control technology and synchronous rectifier. Each device employs a current mode control system to provide a faster transient response to a sudden change in load. Typical applications are a power supply for LSI including DSP, microcomputers, and ASIC.

Features

  • Offers fast transient response with current mode PWM control system
  • Offers highly efficiency for all load range with synchronous rectifier (N-Ch/P-Ch FET) and SLLM™ (Simple Light Load Mode) incorporates soft-start function
  • Incorporates thermal protection and ULVO functions
  • Incorporates short-current protection circuit with time delay function
  • Incorporates shutdown function

Applications

  • Power supply for LSI including DSP, Micro computer and ASIC
