STMicroelectronics L6738 is a highly efficient buck regulator controller designed for step-down DC-DC conversion. This positive output voltage controller IC features a transistor driver output and operates with a switching frequency of up to 200kHz. The L6738 offers robust control features including Enable, Frequency Control, Phase Control, and Power Good signaling, enhancing system stability and monitoring. With a maximum duty cycle of 100%, it ensures optimal power delivery across various load conditions.
The device supports synchronous rectification, contributing to its high efficiency. Its compact 16-VFQFPN (3x3) package with an exposed pad is ideal for surface mount applications, facilitating efficient thermal management. The operating temperature range of -40°C to 125°C (TJ) makes it suitable for demanding environments. The L6738 is commonly employed in power supply designs for consumer electronics, industrial automation, and telecommunications equipment. It operates from a supply voltage range of 5V to 12V and is supplied in trays.
