SGM61020

2A High Efficiency

Synchronous Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM61020 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).

● 2.5V to 5.5V Input Voltage Range

● Adjustable Output Voltage from 0.6V to V_IN

● Up to 95% Efficiency

● Low R_DSONMOSFET Switches (100mΩ/55mΩ)

● Power-Save Mode for Light Load Efficiency

● 42μA (TYP) Operating Quiescent Current

● 100% Duty Cycle Capability for Low Dropout

● 1.5MHz PWM Switching Frequency

● Power Good Output (SGM61020P Only)

● Over-Current Protection

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. The device shutdown current is typically

0.03μA.

● Thermal Shutdown Protection

● Input Under-Voltage Lockout (UVLO) Protection

● Small Packaging:

SGM61020: Available in Green SOT-23-5 and

SOT-563-6 Packages

SGM61020P: Available in a Green SOT-563-6

Package

The SGM61020 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 SGM61020P version only).
