Ultra-High-Efficiency 80 V DC/DC Buck Converter

The BD9G341AEFJ from ROHM is a buck switching regulator with a range of 3 A output current

Image of Rohm's Ultra-High-Efficiency 80V DC/DC Buck ConverterROHM’s BD9G341AEFJ is a buck switching regulator with integrated 150 mΩ power MOSFET. Current-mode architecture provides fast transient response and a simple phase compensation setup. The operating frequency is programmable from 50 kHz to 750 kHz. Additional protection features, such as over-current protection (OCP), thermal-shutdown (TSD), and under-voltage lockout (UVLO), are included. The UVLO and hysteresis can be set by external resistor.

Features
  • OCP, UVLO, TSD, and over-voltage protection (OVP) thermally enhanced HTSOP-J8 package
  • Wide input voltage range from 12 V to 76 V
  • Integrated 80 V/3.5 A/150 mΩ NchFET
  • Current mode
  • Accurate reference voltage (1.0 V ±1.5%)
  • Precision EN threshold (±3%)
  • Soft-start function
  • 0 µA standby current
  • Variable frequency from 50 kHz to 750 kHz
Applications
  • Industrial distributed power applications
  • Automotive applications
  • Battery powered equipment
