SGM66056

2.2MHz, Fixed Output Synchronous

Tiny Boost Converter with a 2.5A Switch

GENERAL DESCRIPTION

FEATURES

The SGM66056 is an internally compensated, 2.2MHz

switching frequency, peak current mode, synchronous

Boost switching converter. This device turns into

power-save mode to maintain high efficiency by lowering

switching frequency. Anti-ringing control circuitry

reduces EMI concerns by damping the inductor in

discontinuous mode. Its output is disconnected by the

rectifier circuit during shutdown with no input to output

leakage.

● Operating Input Voltage Range: 2.5V to 4.5V

● 5.0V Fixed Output Voltage

● 5.7V Output Voltage Clamping

● Up to 93% Efficiency

● Quiescent Current: 34µA (TYP)

● Shutdown Current: 1µA (MAX)

● Improved Light Load Efficiency with Power-Save

Mode (PSM)

● Load Disconnect during Shutdown

● Low Reverse Leakage Current when V_OUT> V_IN

● Thermal Shutdown

● Available in a Green WLCSP-1.21×1.21-9B Package

● -40℃ to +85℃ Operating Temperature Range

The SGM66056 is available in a Green WLCSP-

1.21×1.21-9B package. It operates over an ambient

temperature range of -40℃ to +85℃.
