BD9x Switching Voltage Regulators

ROHM 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.
