Automatically Controlled Buck-Boost Switching Regulator

Description

The BD9035AEFV-C is a buck-boost switching controller with a high withstand voltage and a wide input range (VIN=3.8~30V) capable of generating buck-boost output with one inductor. The IC has a ±7% high accuracy switching frequency for the entire operating temperature range (Ta=-40℃~+125℃). Because of the automatically controlled buck-boost system the BD9035AEFV-C also has a higher efficiency compared to regular switching regulators employing Sepic or H-bridge systems.
