Techcode
Part number
The TD1501S50 is a fixed 5V step-down buck DC/DC converter manufactured by Techcode Semiconductor. It belongs to the TD1501 series, a family of fixed and adjustable switching voltage regulators designed for efficient DC voltage conversion.
The device can drive up to a 3A load, operates with a 150kHz fixed switching frequency, and supports a wide input voltage range. It is commonly used to convert a higher DC input voltage into a stable 5V output rail for embedded systems, industrial electronics, communication devices, consumer electronics, and general power supply circuits. Techcode’s datasheet describes the TD1501 series as easy-to-use fixed and adjustable step-down switch-mode voltage regulators capable of driving a 3A load with good line and load regulation.
