The SGM61020SD and SGM61020PSD are high efficiency synchronous Buck DC/DC converters 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).
The devices operate 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. The device shutdown current is typically 0.5μA (MAX).
The SGM61020SD and SGM61020PSD provide 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 SGM61020PSD only).
The SGM61020SD/SGM61020PSD is available in a Green SOT-563-6 package and can operate in the -40℃ to +125℃ ambient temperature range.
