PRELIMINARY DATASHEET

Synchronous Step-Up

with Ultra Low Quiescent Current

GENERAL DESCRIPTION

FEATURES

The is a synchronous step-up converter

with 0.65μA ultra low quiescent current. It is designed

for products powered by alkaline battery, NiMH

rechargeable battery, Li-Mn battery or rechargeable

Li-Ion battery, for which high efficiency under light load

condition is critical to achieve long battery life

operation.

● Operating Input Voltage from 1.1V to 5.5V

● 0.6µA Ultra Low I_Qinto VOUT Pin

● 0.05µA Ultra Low I_Qinto VIN Pin

● 1.2MHz Fixed Frequency Operation

● Adjustable Output Voltage from 2.5V to 5.4V

● Fixed Output Voltage Versions Available

● Regulated Output Voltage in Down Mode

● True Disconnection During Shutdown

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

Output Voltage Versions

The step-up converter only consumes

0.65μA quiescent current under light load condition and

can achieve up to 75% efficiency at 10μA load with

fixed output voltage version. It can also support up to

300mA output current from 3.3V to 5V conversion, and

achieve up to 93% at 200mA load.

● 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

TDFN-2×2-6AL Packages

The also offers both down mode and

pass-through operation for different applications. In

down mode, the output voltage can still be regulated at

target value even when input voltage is higher than

output voltage. In pass-through mode, the output

voltage follows input voltage. The exits

down mode and enters into pass-through mode when

V_IN> V_OUT+ 0.3V.

APPLICATIONS

Memory LCD Bias

Optical Heart Rate Monitor LED Bias

Wearable Applications

Low Power Wireless Applications

Portable Products

The supports true shutdown function when

it is disabled, which disconnects the load from the input

supply to reduce the current consumption.

The offers both adjustable output voltage

version and fixed output voltage versions. It is available

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

packages.
