Buck Converter

Description

The MT2492 is a fully integrated, high– efficiency 2A synchronous rectified step-down converter. The MT2492 operates at high efficiency over a wide output current load range. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load. The MT2492 requires a minimum number of readily available standard external components and is available in an 6-pin SOT23 ROHS compliant package. Features: High Efficiency: Up to 96% 600KHz Frequency Operation 2A Output Current No Schottky Diode Required 4.5V to 16V Input Voltage Range 0.6V Reference Slope Compensated Current Mode Control for Excellent Line and Load Transient Response Integrated internal compensation Stable with Low ESR Ceramic Output Capacitors Over Current Protection with Hiccup-Mode Thermal Shutdown Inrush Current Limit and Soft Start Available in SOT23-6 Package -40°C to +85°C Temperature Range DataSheet
