STMicroelectronics L5963U-KBT is a highly integrated power management IC featuring three distinct voltage regulation outputs. This device incorporates two synchronous step-down (buck) converters and one linear low-dropout (LDO) regulator, offering a versatile solution for complex power architectures. The synchronous buck converters support a switching frequency range of 250kHz to 2MHz, enabling efficient power conversion across a wide spectrum of operating conditions. The LDO output provides a stable, low-noise voltage rail.
The L5963U-KBT is designed for surface mount applications, utilizing the PowerSO-36 EPU package. Key features include programmable output voltages for the 2.5A and 3A buck outputs, and a 250mA output for the LDO. Integrated functionalities such as a power-on reset sequencer and supervisor enhance system reliability. This component is suitable for demanding applications within the automotive and industrial sectors. The operating temperature range is -40°C to 105°C.
