TYPICAL APPLICATION CIRCUIT
PIC9310
Async Boost with 600KHz
switching
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.
