BD9x Switching Voltage Regulators

ROHM's BD9x regulators provide power efficiency in a variety of compact packages

Image of Rohm's BD9x Switching Voltage RegulatorsROHM Semiconductor's BD9x series offers a compelling solution for designers seeking high-efficiency DC-DC buck converters. These synchronous switching regulators integrate MOSFETs, providing a compact and powerful option for various applications. ROHM BD9x regulators are ideal for a wide range of applications requiring efficient power conversion, including automotive and industrial designs. With their combination of features and benefits, ROHM BD9x switching voltage regulators are a strong choice for designers seeking a compact, efficient, and versatile power solution.

The converter ICs deliver an output current of 1 A to 3 A in the compact TSOT23 package (2.8 mm × 2.9 mm). This reduces component area by up to 72% compared to the general SOP-J8 package (4.9 mm × 6.0 mm), contributing to the miniaturization of power supply blocks. Additionally, adopting a flip chip on lead frame TSOT23 package design enables high-efficiency operation by eliminating bond wire resistance.

Features
  • Integrated MOSFETs: streamlined design with reduced external components
  • Wide input voltage range: 2.7 V to 76 V compatibility for versatility
  • High output current: handles currents from 1 A to 3 A for demanding tasks
  • Fast transient response: delivers consistent performance even with sudden load changes
  • Low standby current: minimizes power consumption during idle periods, ideal for battery-powered devices
  • Constant on-time control: enables efficient operation at light loads
Benefits
  • Simplified design: reduced component count saves space and simplifies manufacturing
  • Power efficiency: low standby current extends battery life in portable applications
  • Excellent regulation: maintains stable output voltage for reliable performance

Applications

  • Automotive
  • Industrial equipment
  • Battery-powered devices
  • Point-of-load (POL) converters
  • Telecommunication systems
