SGM66099

Synchronous Boost Converter

with Ultra-Low Quiescent Current

GENERAL DESCRIPTION

FEATURES

The SGM66099 is an ultra-low quiescent current

synchronous Boost converter. 0.9V to 5.2V operating

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

Li-Ion rechargeable batteries. The 0.6μA (TYP)

quiescent current maximizes the light load efficiency

and also increases the effective battery operation time.

In addition, the high-side synchronous rectifier provides

● Operating Input Voltage Range: 0.9V to 5.2V

● Ultra-Low Quiescent Current



0.6µA (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

● Fixed Output Voltage Versions Available

● Power-Save Mode for Improved Efficiency at Low

Output Power

feature

which

minimizes

unnecessary current drawn from the battery during

shutdown mode.

● Regulated Output Voltage in Down Mode

● True Disconnection During Shutdown

● Up to 75% Efficiency at 10μA Load with Fixed

Output Voltage Version

The SGM66099 is able to deliver 300mA output current

from 3.3V to 5V conversion, and achieves up to 93%

efficiency at 200mA load.

The device offers 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.

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

● -40℃ to +85℃ Operating Ambient Temperature

Range

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

TDFN-2×2-6AL Packages

The device integrates various protection features such

as 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 and LED Bias

Portable and Wearable Applications

Low Power Wireless Applications

Battery Powered Systems

The SGM66099 offers 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.
