The A7121J10R-ADJ from AiT Semiconductor is a Synchronous Buck DC-DC Converter that converts an input voltage of 2.5 - 6 V to an output voltage of over 0.6 V. It has a switching frequency of 1.2 MHz and an efficiency of 95%. This converter supports current mode operation for excellent line and load transient response. It offers an internal soft start that eliminates any output voltage overshoot. This DC-DC converter can run at 100% duty cycle for low dropout operation, extending battery life in portable systems.

This buck converter integrates short-circuit and thermal fault protection to prevent short-circuit or false trigger-related damages. This RoHS-compliant converter is available in a surface-mount package that measures 3.1 x 3.1 x 0.9 mm and is ideal for cellular phones, digital cameras, DSP core supplies, printers, portable instruments and xDSL applications.
