STMICROELECTRONICS DC-DC Switching Buck Step Down Regulator Adjustable HSOP-8 - 4V 36V 1.235V 35V 2.5A
High-efficiency STMICROELECTRONICS buck regulator IC. 4-36V input, 1.235-35V adjustable output, 2A current. Surface mount HSOP-8 package.
The STMICROELECTRONICS DC-DC Switching Buck Step Down Regulator is a high-performance, monolithic power management IC designed for efficient voltage conversion in a compact surface-mount package. Based on the advanced L5973AD chip, this regulator utilises an internal P-channel D-MOS transistor as the switching element, eliminating the need for a bootstrap capacitor and enabling exceptionally high efficiency, typically around 90%. With a robust switch current limit of 2A, it is capable of delivering over 1.5A DC to the load, making it a reliable power source for a wide array of electronic applications.
Engineered for stability and protection, this device incorporates several sophisticated features to ensure safe and reliable operation. It offers pulse-by-pulse current limiting combined with internal frequency modulation, providing effective constant-current short-circuit protection. Additional safeguards include thermal shutdown and protection against feedback disconnection, enhancing the longevity and durability of both the regulator and the end product. The inclusion of an inhibit function allows for near-zero current consumption during standby or off modes, which is ideal for power-sensitive designs.
