DIO6199B

Synchronous Boost Converter with Ultra-Low Quiescent

Current

Features

Descriptions



Operating input voltage range: 1.1V to 5.5V

DIO6199B is a synchronous boost converter with

2µA ultra-low quiescent current. It can operate

efficiently under light load conditions, which is

essential to prolong the service life of batteries.

DIO6199B boost converter adopts Constant Off

Time (COT) control topology, which can achieve

the highest efficiency with the lowest quiescent

current. The device consumes only 2µA quiescent

current under light load.



Adjustable output voltage range: 2.0V to

5.5V



Ultra−Low quiescent current (V_OUTPin):

800nA

Ultra−Low quiescent current (V_INPin):

600nA

load

DIO6199B can also provide Down mode and Pass-

through mode for different applications. In Down

mode, even if the input voltage is higher than the

output voltage, the output voltage can be adjusted

as the target value. In Pass-through mode, the

output voltage varies with the input voltage. When

V_IN>V_OUT+0.5V, DIO6199B exits the Down mode

and transfers to Pass-through through mode.

DIO6199B can disconnect the load from the input

power supply when it is disabled, thus realizing the

real shutdown, thus reducing the current

consumption. The device is packaged in DFN2*2-6

and SOT23-6.
