The STMicroelectronics L4964HT is a high-current, adjustable positive buck switching regulator designed for efficient power conversion. This device offers a high output current capability of 4A and an adjustable output voltage ranging from 5.1V up to 28V, with a fixed initial output of 5.1V. Operating with a switching frequency of 50kHz, it is suitable for applications requiring a stable step-down voltage. The L4964HT features a wide input voltage range from 9V to 36V, making it versatile for various power supply designs. Its non-synchronous buck topology is housed in a 15-Multiwatt package, a through-hole mounting type with horizontal, bent, and staggered leads for robust integration. This component is widely utilized in automotive, industrial, and consumer electronics sectors where reliable and efficient voltage regulation is critical. The extended operating temperature range of -40°C to 150°C (TJ) ensures performance in demanding environments.
