SGM66055B

2.2MHz, Fixed Output Synchronous

Tiny Boost Converter with a 2.4A Switch

GENERAL DESCRIPTION

FEATURES

 2.5V to 4.85V Operating Input Voltage Range

 5.0V Fixed Output Voltage

The SGM66055B is an internally compensated, 2.2MHz

switching frequency, current mode, synchronous Boost

switching converter. The SGM66055B supports up to

800mA load current from a battery as low as 2.65V,

and the output voltage is fixed at 5.0V. This device turns

into power-save mode to maintain high efficiency at light

load currents. Its output is disconnected by the rectifier

circuit during shutdown with no input to output leakage.

 I_OUT≥ 1A at V_OUT= 5V, V_IN≥ 2.7V

 Up to 97% Efficiency

 Device Quiescent Current: 24µA (TYP)

 Shutdown Current: 1µA (MAX)

 Improved Light Load Efficiency with Power-Save

Mode (PSM)

 Low Reverse Leakage Current when V_OUT> V_IN

 Load Disconnect during Shutdown

 Thermal Shutdown

The SGM66055B has built-in protection features such

as short-circuit protection, over-current protection and

thermal shutdown.

 -40℃ to +85℃ Operating Temperature Range

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

The SGM66055B is available in a Green WLCSP-

1.21×1.21-9B package.
