Texas Instruments LM2677S-ADJ is a SIMPLE SWITCHER® buck switching regulator designed for efficient step-down voltage conversion. This device offers an adjustable output voltage, ranging from a minimum of 1.21V up to 37V, with a maximum output current capability of 5A. The internal switch architecture operates at a switching frequency of 260kHz, enabling the use of smaller external components. Featuring a non-synchronous buck topology, the LM2677S-ADJ requires minimal external components for operation and is suitable for applications requiring a positive output. It is housed in a TO-263-8, D2PAK (7 Leads + Tab) surface-mount package. The operational input voltage range is from 8V to 40V, and it is specified for operation across an ambient temperature range of -40°C to 125°C. This component is commonly utilized in power supply designs across various industrial and consumer electronics sectors.
