DESCRIPTION

The PIC9310 compact, high-efficiency, step-up DC-

DC converters are available in tiny, 6-pin thin

SOT26 packages. They feature an extremely low

5µA quiescent supply current to ensure the highest

possible

light-load

efficiency.

Optimized

for

operation from one to two alkaline or nickel-metal-

hydride (NiMH) cells, or a single Li+ cell, these

devices are ideal for applications where extremely

low quiescent current and ultra-small size are

critical.

The PIC9310 also feature proprietary noise-

reduction

circuitry,

which

suppresses

electromagnetic interference (EMI) caused by the

inductor in many step-up applications. The family

offers different combinations of fixed outputs,

shutdown, and EMI reduction (see Selector Guide).

Its unique design is optimized for high efficiency at

light load condition.

TYPICAL APPLICATION CIRCUIT

Async Boost with 600KHz

switching
