SGM66099B

Synchronous Boost Converter

with Ultra-Low Quiescent Current

GENERAL DESCRIPTION

FEATURES

The SGM66099B is an ultra-low quiescent current

synchronous Boost converter. 1.15V to 5.2V operation

input voltage is suitable for Li-Mn battery, NiMH and

Li-Ion rechargeable batteries. The 1.7μA (TYP) quiescent

current maximizes the light load efficiency and also

increases the effective battery operation time. In

addition, the high-side synchronous rectifier provides

output disconnect feature which minimizes unnecessary

current drawn from the battery during shutdown mode.

● Operating Input Voltage Range: 1.15V to 5.2V

● Ultra-Low Quiescent Current

 1.7µA (TYP) Ultra-Low I_Qinto VOUT Pin

 0.05µA (TYP) Ultra-Low I_Qinto VIN Pin

● 1.2MHz Fixed Frequency Operation

● Adjustable Output Voltage from 2.5V to 5.2V

● 5.0V Fixed Output Voltage Version

● Power-Save Mode for Improved Efficiency at Low

Output Power

The SGM66099B is able to deliver 300mA output

current from 3.3V to 5V conversion, and achieves up to

93% efficiency at 200mA load.

● Regulated Output Voltage in Down Mode

● True Disconnection During Shutdown

● Up to 93% Efficiency from 10mA to 300mA Load

● -40℃ to +85℃ Operating Temperature Range

● Available in Green WLCSP-1.22×0.83-6B and

The device provides down mode where the desired

output voltage is regulated even when input voltage is

higher than the output. In addition, when the input

voltage is 300mV above the output voltage set point,

the device enters pass-through mode.

TDFN-2×2-6AL Packages

The device integrates various protection features such

as over-current protection, over-voltage protection and

thermal shutdown. In addition, the synchronous rectifier

supports short circuit protection which further improves

the robustness of the device.

APPLICATIONS

LCD Bias

Optical Heart Rate Monitor LED Bias

Portable and Wearable Applications

Battery Powered Systems

The SGM66099B provides both adjustable output

voltage and fixed output voltage versions. It is available

in Green WLCSP-1.22×0.83-6B and TDFN-2×2-6AL

packages.
