The PC8609 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.

The PC8609 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% efficiency at 200mA load.

The PC8609 also offers both down mode

andpass-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 PC8609 exits

down mode and enters into pass-through mode when

VIN > VOUT + 0.3V.

The PC8609 supports true shutdown function when it

is disabled, which disconnects the load from the input

supply to reduce the current consumption. The

PC8609 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.
