ROHM BD9B333GWZE2 Synchronous Buck Converter

BD9B333GWZ is a high-frequency, synchronous buck DC/DC converter capable of delivering up to 3A with input voltage from 2.7V to 5.5V. It features built-in low Rds(on) power MOSFETs, fast transient response, and operates at a typical switching frequency of 1.3MHz. Designed for low standby power consumption, it employs constant on-time control mode, suitable for step-down power supplies in compact electronic devices such as DSPs, FPGAs, laptops, and storage equipment. Its small UCSP35L1 CSP package offers high power density, thermal shutdown, overcurrent, overvoltage, and undervoltage protections, making it ideal for space-constrained applications requiring reliable power conversion.
