SGM61020S 2A High Efficiency Synchronous Buck Converter
●The SGM61020S is a high efficiency synchronous Buck DC/DC converter with 2A output current capability and adjustable output voltage. The input supply voltage is in the range of 2.5V to 5.5V. Using adaptive off-time peak current control, the efficiency of this device is higher than 80% for loads over 1mA and reaches 95% in the moderate load ranges (5V to 3.3V).
●This device operates with a quasi-fixed 1.5MHz pulse width modulation (PWM) mode for moderate or heavy loads. But at light loads, pulse skip modulation is used for power-save mode (PSM). The PSM operating quiescent current is very low, typically 44μA, which is well suitable for battery powered applications to prolong battery life. Despite such low quiescent current, the transient response to large load variations is excellent. The device shutdown current is less than 0.5μA.
●The SGM61020S provides an adjustable output voltage by an external resistor divider. The device is capable for low dropout operation with 100% duty cycle. Some other features include internal soft-start for limiting startup inrush current, over-current and thermal shutdown protections, enable input and power good output (for SGM61020PS version only).
●The SGM61020S is available in a Green SOT-23-5 package and the SGM61020PS is available in a Green SOT-23-6 package.
