STMicroelectronics STBB2J29-R is a highly efficient, synchronous buck-boost switching regulator designed for applications requiring flexible voltage conversion. This positive output IC operates with a minimum input voltage of 2.4V and a maximum of 5.5V. It delivers a programmable output voltage, with fixed options at 2.9V and 3.4V, and supports a continuous output current of 800mA. The device features a 2.5MHz switching frequency and a buck-boost topology, enabling it to step voltage up or down from the input. Its 20-UFBGA, FCBGA package with a 20-Flip-Chip (2.1x1.8) footprint is suitable for surface mount applications. The STBB2J29-R is utilized in power-sensitive systems such as portable electronics, wearables, and IoT devices where optimal power management is critical. It operates across a temperature range of -40°C to 85°C (TA) and is supplied in Tape & Reel (TR) packaging.
