DESCRIPTION

The ST5R00 is an high efficiency VFM Step-up

DC/DC converter for small, low input voltage or

battery powered systems with ultra low quiescent

supply current. The ST5Rxx accept a positive

input voltage from start-up voltage to VOUT and

convert it to a higher output voltage in the 2.5 to

5V range.

The ST5R00 combine ultra low quiescent supply

current and high efficiency to give maximum

battery life. The high switching frequency and the

internally limited peak inductor current, permits

the use of small, low cost inductors. Only three

external components are needed: an inductor a

diode and an output capacitor.

The ST5R00 is suitable to be used in a battery

powered equipment where low noise, low ripple

and ultra low supply current are required. The

ST5R00 is available in very small packages:

SOT23-5L.

Typical applications are pagers, cameras & video

camera, cellular telephones, wireless telephones,

palmtop

computer,

battery

backup

supplies,

battery powered equipment.
