SGM61020XN5G/TR

SGM61020XN5G/TR 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 42µA, which is well suitable for battery-powered applications to increase standby time. Despite such low quiescent current, the transient response to large load variations is excellent. Application includes battery-Powered Applications point-of-load, processor power supplies, hard disk drives (HDD)/solid state drives (SSD).
