The A7222AE6VR from AiT Semiconductor is a Synchronous Buck DC-DC Converter that requires an input voltage of 4.5 - 16 V. This converter has a switching frequency of 500 kHz and an efficiency of up to 96%. It uses 0.6 V reference and slope-compensated current mode control to ensure excellent line and load transient response. This DC-DC converter offers integrated internal compensation and stability with low-ESR ceramic output capacitors. It includes over-current protection with hiccup mode, thermal shutdown, an inrush current limit, and soft start functionalities to ensure high reliability and safety during operation. This converter offers pulse width modulation (PWM) control and pulse frequency modulation (PFM) mode switching control operation modes. It is available in a surface-mount package that measures 2.9 x 2.8 mm and is ideal for distributed power systems, digital set-top boxes, flat-panel televisions and monitors, wireless and DSL modems, and notebook computer applications.
