SGM61230 4.5V to 28V Input, 3A Output, Synchronous Buck Converter GENERAL DESCRIPTION FEATURES The SGM61230 is a synchronous Buck converter with a wide input voltage range of 4.5V to 28V. This device can deliver up to 3A to the output over a wide input voltage. It is an easy-to-use device with power switches and peak current mode control compensation all integrated in a small 6-pin package. A typical 5ms soft-start ramp is also included to minimize the inrush current. This device employs cycle-by-cycle peak current limit, output over-voltage protection and thermal shutdown with auto recovery. The current limit is implemented for both switches and has foldback feature to prevent overheating (and thermal shutdown) when an output short is detected. Auto recovery after over-current, output short, overheating or over-voltage fault maintains the system operational with no shutdown. This converter has a fixed 410kHz switching frequency that minimizes the EMI noise problems. However the actual frequency drops during PSM (pulse skip mode) to maximize efficiency at light load. It also drops in some fault conditions. The SGM61230 is available in a Green TSOT-23-6 package. ● Wide 4.5V to 28V Input Voltage Range ● 3A Continuous Output Current ● Integrated 66mΩ/36mΩ Power MOSFETs ● Low Quiescent Current: 25μA (TYP) ● Shutdown Current: 2μA (TYP) ● 5ms Internal Soft-Start Time ● Fixed 410kHz Switching Frequency ● Pulse Skip Mode and PWM Mode ● Peak Current Mode Control ● Internal Loop Compensation ● Over-Current Protection for Both MOSFETs ● Output Over-Voltage Protection ● Adjustable Input Under-Voltage Lockout ● Thermal Shutdown with Auto Recovery ● Available in a Green TSOT-23-6 Package APPLICATIONS 12V Distributed Power Supply Buses Industrial and Consumer Applications White Goods Audio Equipment Set Top Boxes Digital Television Printers TYPICAL APPLICATION BOOT VIN VIN CBOOT CIN SW SGM61230 EN VOUT L COUT RFB1 FB GND RFB2 Figure 1.
