M3TEK IT7832 5V/2A High Efficiency Step-Down DC/DC Converter Description The IT7832 is a low-input voltage and high-output current synchronous-buck PWM converter and integrates with all required active components. Its’ operating input voltage ranges from 2.7V to 6V and output voltage ranges from VIN down to 0.8V. The switching frequency is adjustable ranging from 300kHz to 1.4MHz. High performance and externally compensation voltage error amplifier provides design flexibility and high performance under transient. In addition,it provides internal soft-start to reduce inrush-current, current-limit and thermal shutdown, preventing IC from being damaged. If the EN pin is floating, it will be pulled high by the internal circuit. Features 2.7V to 6V Input Voltage Range 2A Output Current Typical Quiescent Current: 0.65mA 300kHz to 1.4MHz Adjustable Frequency Operation 0.8V to VIN Adjustable Output Voltage 100% Duty Cycle for Lowest Dropout 0% Duty Cycle External Compensation Internal Soft-Start Enable Internal Pull High.
