ROHM Semiconductor USA, LLC Voltage Regulators - DC DC Switching Regulators BD91501MUV-GE2

The BD91501MUV-GE2 is a dual-channel synchronous buck converter designed to provide stable output voltages of 2.55V at 0.4A and 1.8V at 0.3A from a 3.3V input supply. It features high efficiency across all load ranges, utilizing a synchronous rectifier and ROHM's proprietary pulse skip control technology. The device employs current mode PWM control for fast transient response to load changes, making it suitable for applications requiring quick adjustments in power delivery. Key specifications include an input voltage range of 2.55V to 5.5V, an output voltage accuracy of ¬±1.5%, and a switching frequency of 1.65MHz. The operating temperature range is from -30¬8C to +105¬8C, ensuring reliability in various environments. Additional features include soft start functionality, thermal protection, under-voltage lockout (UVLO), and short-circuit protection with a timer latch. The device is packaged in a compact VQFN016V3030 surface mount package, measuring 3.00mm x 3.00mm x 1.00mm, which facilitates integration into space-constrained designs. This regulator is suitable for powering LSIs, including DSPs, DDR RAM, microcontrollers, and ASICs.
