The BD9322EFJ-E2 from ROHM Semiconductor is a highly integrated step-down switching regulator. It features a built-in low resistance high-side N-channel MOSFET, enabling it to deliver up to 2A of continuous output current.
This regulator operates over a wide input voltage range of 4.75V to 18V and has a fixed operating frequency of 380kHz. Current mode operation ensures fast transient response and simplifies phase compensation. The device includes essential protection circuits such as undervoltage lockout, thermal shutdown, and overcurrent protection.
Designed for applications like distributed power systems and pre-regulation for linear regulators, the BD9322EFJ-E2 is housed in an 8-HTSOP-J package with an exposed thermal pad for improved heat dissipation. It supports surface mount installation and is suitable for environments operating between -40°C and 85°C.
Key electrical characteristics include a typical feedback voltage accuracy of 0.9V ±1.5% and a typical on-resistance of 0.15Ω for the internal MOSFET at -0.8A. The switch current limit for the BD9322EFJ is 2.5A.
