SGM66051

Efficient Synchronous

Boost Converter with a 2.7A Switch

GENERAL DESCRIPTION

FEATURES

The SGM66051 is an internally compensated, 1.1MHz

switching frequency, current mode, synchronous Boost

switching regulator, which is capable of generating 5V

output at 1A load current from a 3.3V rail. This device

also has the 5.1V and 5.4V fixed output version.

● 2.2V to 5.5V Input Voltage Range

● 5.1V and 5.4V Fixed Output Voltages

● Adjustable Output Voltage up to 5.5V

● Up to 90% Efficiency

● 20µA (TYP) Quiescent Current

This device turns into power-saving mode to maintain

high efficiency by lowering switching frequency. With its

anti-ringing circuitry damping the charge in parasitic

capacitor, it reduces EMI interference significantly. Its

output is disconnected by the rectifier circuit during

shutdown, with no input to output leakage.

● 1µA (MAX) Shutdown Current

● 6V Output Voltage Clamping

● Improved Light Load Efficiency with Power-Save

Mode (PSM)

● Load Disconnect during Shutdown

● Low Reverse Leakage Current when V_OUT> V_IN

● Over-Temperature Protection

The SGM66051-5.1 and SGM66051-5.4 are preset for

outputting 5.1V and 5.4V, while the SGM66051-ADJ is

output voltage programmable with an external resistor

divider.

● Available in a Green TSOT-23-6 Package

● -40℃ to +85℃ Operating Temperature Range

The device is available in a Green TSOT-23-6 package

and operates over an ambient temperature range of -40℃

to +85℃.
