STMicroelectronics L5963DN-EHT is a power management integrated circuit featuring three distinct voltage regulator outputs. This device integrates two synchronous step-down (buck) converters and one linear low-dropout (LDO) regulator. The synchronous buck converters offer high efficiency and adjustable switching frequencies ranging from 250kHz to 2MHz. Output 1 is capable of delivering up to 2.5A, while Output 2 supports up to 3A, with programmable voltage settings for both. The integrated LDO regulator provides a stable output of 250mA, also with programmable voltage. The L5963DN-EHT includes a power-on reset sequencer and supervisor functions, enhancing system reliability. It is housed in a 36-PowerSSO-36 EPU package suitable for surface mounting and operates across a temperature range of -40°C to 105°C. This component is utilized in automotive applications, industrial control systems, and consumer electronics requiring robust power management.
